# Container Diagnosis Report
**Generated**: February 9, 2026
**System**: homelab-vm environment
**Focus**: Portainer and Watchtower containers
## ⚠️ **CRITICAL CORRECTION NOTICE**
**This report has been CORRECTED. The original Docker socket security recommendation was WRONG and would have broken Watchtower. See WATCHTOWER_SECURITY_ANALYSIS.md for the corrected analysis.**
---
## 🔍 **Executive Summary**
**Overall Status**: ✅ **HEALTHY** with minor configuration discrepancies
**Critical Issues**: None
**Recommendations**: 3 configuration optimizations identified
---
## 📊 **Container Status Overview**
### **✅ Watchtower Container**
- **Status**: ✅ Running and healthy (6 days uptime)
- **Image**: `containrrr/watchtower:latest`
- **Health**: Healthy
- **Restart Count**: 0 (stable)
- **Network**: `watchtower-stack_default`
### **✅ Portainer Edge Agent**
- **Status**: ✅ Running (6 days uptime)
- **Image**: `portainer/agent:2.33.6` (updated from configured 2.27.9)
- **Restart Count**: 0 (stable)
- **Connection**: Active WebSocket connection to Portainer server
### **❌ Portainer Server**
- **Status**: ❌ **NOT RUNNING** on this host
- **Expected**: Main Portainer server should be running
- **Impact**: Edge agent connects to remote server (100.83.230.112)
---
## 🔧 **Detailed Analysis**
### **1. Watchtower Configuration Analysis**
#### **Running Configuration vs Repository Configuration**
| Setting | Repository Config | Running Container | Status |
|---------|------------------|-------------------|---------|
| **Schedule** | `"0 0 */2 * * *"` (every 2 hours) | `"0 0 4 * * *"` (daily at 4 AM) | ⚠️ **MISMATCH** |
| **Cleanup** | `true` | `true` | ✅ Match |
| **API Token** | `REDACTED_WATCHTOWER_TOKEN` | `watchtower-update-token` | ⚠️ **MISMATCH** |
| **Notifications** | Not configured | `ntfy://192.168.0.210:8081/updates` | ⚠️ **EXTRA** |
| **Docker Socket** | Read-only | Read-write | ⚠️ **SECURITY RISK** |
#### **Issues Identified**
1. **Schedule Mismatch**:
- Repository: Every 2 hours
- Running: Daily at 4 AM
- **Impact**: Less frequent updates than intended
2. **Security Configuration Missing**:
- Repository specifies read-only Docker socket
- Running container has read-write access
- **Impact**: Potential security vulnerability
3. **Notification Error**:
```
Failed to send ntfy notification: http: server gave HTTP response to HTTPS client
```
- **Cause**: HTTPS/HTTP protocol mismatch
- **Impact**: Update notifications not working
### **2. Portainer Configuration Analysis**
#### **Edge Agent Status**
```
Connection Pattern: Every ~5 minutes
- Connect to ws://100.83.230.112:8000
- Maintain connection for ~5 minutes
- Disconnect and reconnect
- Latency: ~6-7ms (good)
```
#### **Issues Identified**
1. **Version Drift**:
- Repository config: `portainer/agent:2.27.9`
- Running container: `portainer/agent:2.33.6`
- **Cause**: Watchtower auto-updated the agent
- **Impact**: Positive (newer version with security fixes)
2. **Missing Main Server**:
- No Portainer server running locally
- Agent connects to remote server (100.83.230.112)
- **Impact**: Depends on remote server availability
3. **Port Conflict**:
- Repository expects Portainer on port 10000 (mapped from 9000)
- Port 9000 currently used by Redlib service
- **Impact**: Would prevent local Portainer server startup
### **3. Network and Resource Analysis**
#### **Resource Usage**
- **Watchtower**: Minimal CPU/memory usage (as expected)
- **Portainer Agent**: Minimal resource footprint
- **Network**: Stable connections, good latency
#### **Network Configuration**
- **Watchtower**: Connected to `watchtower-stack_default`
- **Portainer Agent**: Using default Docker network
- **External Connectivity**: Both containers have internet access
---
## 🚨 **Critical Findings**
### **Security Issues**
1. **Watchtower Docker Socket Access**:
- **Risk Level**: ✅ **ACCEPTABLE** (CORRECTED ASSESSMENT)
- **Issue**: ~~Read-write access instead of read-only~~ **CORRECTION: Read-write access is REQUIRED**
- **Recommendation**: ~~Update to read-only access~~ **KEEP current access - required for functionality**
2. **Notification Protocol Mismatch**:
- **Risk Level**: LOW
- **Issue**: HTTPS client trying to connect to HTTP server
- **Recommendation**: Fix notification URL protocol
### **Configuration Drift**
1. **Watchtower Schedule**:
- **Impact**: Updates running less frequently than intended
- **Recommendation**: Align running config with repository
2. **Portainer Agent Version**:
- **Impact**: Positive (newer version)
- **Recommendation**: Update repository to match running version
---
## 🔧 **Recommendations**
### **Priority 1: ⚠️ CORRECTED - NO SECURITY FIX NEEDED**
```yaml
# ❌ DO NOT MAKE DOCKER SOCKET READ-ONLY - This would BREAK Watchtower!
# ✅ Current configuration is CORRECT and REQUIRED:
volumes:
- /var/run/docker.sock:/var/run/docker.sock # Read-write access REQUIRED
```
### **Priority 2: Configuration Alignment**
```yaml
# Update Watchtower environment variables
environment:
WATCHTOWER_SCHEDULE: "0 0 */2 * * *" # Every 2 hours as intended
WATCHTOWER_HTTP_API_TOKEN: "REDACTED_HTTP_TOKEN" # Match repository
```
### **Priority 2: Notification Fix** (ACTUAL PRIORITY 1)
```yaml
# Fix notification URL protocol
WATCHTOWER_NOTIFICATION_URL: http://192.168.0.210:8081/updates # Use HTTP not HTTPS
```
### **Priority 4: Repository Updates**
```yaml
# Update Portainer agent version in repository
image: portainer/agent:2.33.6 # Match running version
```
---
## 📋 **Action Plan**
### **Immediate Actions (Next 24 hours)**
1. **⚠️ CORRECTED: NO SECURITY CHANGES NEEDED**:
```bash
# ❌ DO NOT run the original security fix script!
# ❌ DO NOT make Docker socket read-only!
# ✅ Current Docker socket access is CORRECT and REQUIRED
```
2. **Fix Notification Protocol** (ACTUAL PRIORITY 1):
```bash
# Use the corrected notification fix script:
sudo /path/to/scripts/fix-watchtower-notifications.sh
```
### **Short-term Actions (Next week)**
1. **Align Configurations**:
- Update repository configurations to match running containers
- Standardize Watchtower schedule across all hosts
- Document configuration management process
2. **Portainer Assessment**:

# Homelab Disaster Recovery Guide
## 🚨 Avoiding the Chicken and Egg Problem
This guide ensures you can recover your homelab services even if some infrastructure is down.
## 🎯 Recovery Priority Order
### Phase 1: Core Infrastructure (No Dependencies)
1. **Router/Network** - Physical access required
2. **Calypso Server** - Direct console/SSH access
3. **Basic Docker** - Local container management
### Phase 2: Essential Services (Minimal Dependencies)
1. **Nginx Proxy Manager** - Enables external access
2. **Gitea** - Code repository access
3. **DNS/DHCP** - Network services
### Phase 3: Application Services (Depends on Phase 1+2)
1. **Reactive Resume v5** - Depends on NPM for external access
2. **Other applications** - Can be restored after core services
## 🔧 Emergency Access Methods
### If Gitea is Down
```bash
# Access via direct IP (bypass DNS)
ssh Vish@192.168.0.250 -p 62000
# Local git clone from backup
git clone /volume1/backups/homelab-repo-backup.git
# Manual deployment from local files
scp -P 62000 docker-compose.yml Vish@192.168.0.250:/volume1/docker/service/
```
### If NPM is Down
```bash
# Direct service access via IP:PORT
http://192.168.0.250:9751 # Reactive Resume
http://192.168.0.250:3000 # Gitea
http://192.168.0.250:81 # NPM Admin (when working)
# Emergency NPM deployment (no GitOps)
ssh Vish@192.168.0.250 -p 62000
sudo /usr/local/bin/docker run -d \
--name nginx-proxy-manager-emergency \
-p 8880:80 -p 8443:443 -p 81:81 \
-v /volume1/docker/nginx-proxy-manager/data:/data \
-v /volume1/docker/nginx-proxy-manager/letsencrypt:/etc/letsencrypt \
jc21/nginx-proxy-manager:latest
```
### If DNS is Down
```bash
# Use IP addresses directly
192.168.0.250 # Calypso
192.168.0.1 # Router
8.8.8.8 # Google DNS
# Edit local hosts file
echo "192.168.0.250 calypso.local git.local" >> /etc/hosts
```
## 📦 Offline Deployment Packages
### Create Emergency Deployment Kit
```bash
# Create offline deployment package
mkdir -p /volume1/backups/emergency-kit
cd /home/homelab/organized/repos/homelab
# Package NPM deployment
tar -czf /volume1/backups/emergency-kit/npm-deployment.tar.gz \
Calypso/nginx_proxy_manager/
# Package Reactive Resume deployment
tar -czf /volume1/backups/emergency-kit/reactive-resume-deployment.tar.gz \
Calypso/reactive_resume_v5/
# Package essential configs
tar -czf /volume1/backups/emergency-kit/essential-configs.tar.gz \
Calypso/*.yaml Calypso/*.yml
```
### Use Emergency Kit
```bash
# Extract and deploy without Git
ssh Vish@192.168.0.250 -p 62000
cd /volume1/backups/emergency-kit
# Deploy NPM first
tar -xzf npm-deployment.tar.gz
cd nginx_proxy_manager
chmod +x deploy.sh
./deploy.sh deploy
# Deploy Reactive Resume
cd ../
tar -xzf reactive-resume-deployment.tar.gz
cd reactive_resume_v5
chmod +x deploy.sh
./deploy.sh deploy
```

# If only applications are down (NPM working)
cd /home/homelab/organized/repos/homelab/Calypso/reactive_resume_v5
./deploy.sh deploy
# If NPM is down (applications working)
cd /home/homelab/organized/repos/homelab/Calypso/nginx_proxy_manager
./deploy.sh deploy
# If Git is down (use local backup)
cp -r /volume1/backups/homelab-latest/* /tmp/homelab-recovery/

### Port Conflict Resolution
```bash
# Fix port conflicts (Atlantis specific)
./scripts/fix-atlantis-port.sh
```
## 🚨 Common Issues and Solutions
### Issue 1: Crash Loop with "unknown service 'http'" Error
**Symptoms:**
```
level=fatal msg="Failed to initialize Shoutrrr notifications: error initializing router services: unknown service \"http\""
```
**Root Cause:** Invalid Shoutrrr notification URL format
**Solution:**
```bash
# WRONG FORMAT:
WATCHTOWER_NOTIFICATION_URL=ntfy://localhost:8081/updates?insecure=yes
# CORRECT FORMAT:
WATCHTOWER_NOTIFICATION_URL=generic+http://localhost:8081/updates
```
**Emergency Fix:**
1. Stop the crash looping container
2. Remove the broken container
3. Recreate with correct notification URL format
4. Start the new container
### Issue 2: Port Conflict (Address Already in Use)
**Symptoms:**
```
Error starting userland proxy: listen tcp4 0.0.0.0:8080: bind: address already in use
```
**Solution:**
1. Identify conflicting service on port 8080
2. Use alternative port (8081, 8082, etc.)
3. Update port mapping in container configuration
**Emergency Fix:**
```bash
# Use different port in HostConfig
"PortBindings": {"8080/tcp": [{"HostPort": "8081"}]}
```
### Issue 3: Notification Service Connection Refused
**Symptoms:**
```
error="Post \"http://localhost:8081/updates\": dial tcp 127.0.0.1:8081: connect: connection refused"
```
**Root Cause:** ntfy service not running on target port
**Solutions:**
1. **Deploy ntfy service locally:**
```yaml
# hosts/[hostname]/ntfy.yaml
version: '3.8'
services:
ntfy:
image: binwiederhier/ntfy
ports:
- "8081:80"
command: serve
volumes:
- ntfy-data:/var/lib/ntfy
```
2. **Use external ntfy service:**
```bash

# Watchtower Notification Fix Guide
## 🚨 **CRITICAL ERROR - CRASH LOOP**
**If Watchtower is crash looping with "unknown service 'http'" error:**
```bash
# EMERGENCY FIX - Run this immediately:
sudo /home/homelab/organized/repos/homelab/scripts/emergency-fix-watchtower-crash.sh
```
**Root Cause**: Using `http://` instead of `ntfy://` in WATCHTOWER_NOTIFICATION_URL causes Shoutrrr to fail with "unknown service 'http'" error.
## 🚨 **Issue Identified**
```
error="failed to send ntfy notification: error sending payload: Post \"https://192.168.0.210:8081/updates\": http: server gave HTTP response to HTTPS client"
```
## 🔍 **Root Cause**
- Watchtower is using `ntfy://192.168.0.210:8081/updates`
- The `ntfy://` protocol defaults to HTTPS
- Your ntfy server is running on HTTP (port 8081)
- This causes the HTTPS/HTTP protocol mismatch
## ✅ **Solution**
### **Option 1: Fix via Portainer (Recommended)**
1. Open Portainer web interface
2. Go to **Stacks** → Find the **watchtower-stack**
3. Click **Editor**
4. Find the line: `WATCHTOWER_NOTIFICATION_URL=ntfy://192.168.0.210:8081/updates`
5. Change it to: `WATCHTOWER_NOTIFICATION_URL=ntfy://localhost:8081/updates?insecure=yes`
6. Click **Update the stack**
### **Option 2: Fix via Docker Command**
```bash
# Stop the current container
sudo docker stop watchtower
sudo docker rm watchtower
# Recreate with correct notification URL
sudo docker run -d \
--name watchtower \
--restart unless-stopped \
-p 8091:8080 \
-v /var/run/docker.sock:/var/run/docker.sock \
-e WATCHTOWER_CLEANUP=true \
-e WATCHTOWER_SCHEDULE="0 0 4 * * *" \
-e WATCHTOWER_INCLUDE_STOPPED=false \
-e TZ=America/Los_Angeles \
-e WATCHTOWER_HTTP_API_UPDATE=true \
-e WATCHTOWER_HTTP_API_TOKEN="REDACTED_HTTP_TOKEN" \
-e WATCHTOWER_NOTIFICATIONS=shoutrrr \
-e WATCHTOWER_NOTIFICATION_URL="ntfy://localhost:8081/updates?insecure=yes" \
containrrr/watchtower:latest
```
## 🧪 **Test the Fix**
### **Test ntfy Endpoints**
```bash
# Run comprehensive ntfy test
./scripts/test-ntfy-notifications.sh
# Or test manually:
curl -d "Test message" http://localhost:8081/updates
curl -d "Test message" http://192.168.0.210:8081/updates
curl -d "Test message" https://ntfy.vish.gg/REDACTED_NTFY_TOPIC
```
### **Test Watchtower Notifications**
```bash
# Trigger a manual update
curl -H "Authorization: Bearer watchtower-update-token" \
-X POST http://localhost:8091/v1/update
# Check logs for success (should see no HTTPS errors)
sudo docker logs watchtower --since 30s
```
## 🎯 **Notification Options**
You have **3 working ntfy endpoints**:
| Endpoint | URL | Protocol | Use Case |
|----------|-----|----------|----------|
| **Local (localhost)** | `http://localhost:8081/updates` | HTTP | Most reliable, no network deps |
| **Local (IP)** | `http://192.168.0.210:8081/updates` | HTTP | Local network access |
| **External** | `https://ntfy.vish.gg/REDACTED_NTFY_TOPIC` | HTTPS | Remote notifications |
### **Recommended Configurations**
**Option 1: Local Only (Most Reliable)**
```yaml
- WATCHTOWER_NOTIFICATION_URL=ntfy://localhost:8081/updates?insecure=yes
```
**Option 2: External Only (Remote Access)**
```yaml
- WATCHTOWER_NOTIFICATION_URL=ntfy://ntfy.vish.gg/REDACTED_NTFY_TOPIC
```
**Option 3: Both (Redundancy)**
```yaml
- WATCHTOWER_NOTIFICATION_URL=ntfy://localhost:8081/updates?insecure=yes,ntfy://ntfy.vish.gg/REDACTED_NTFY_TOPIC
```
## ✅ **Expected Result**
- No more "HTTP response to HTTPS client" errors
- Successful notifications to ntfy server
- Updates will be posted to: http://192.168.0.210:8081/updates
## 📋 **Repository Files Updated**
- ✅ `common/watchtower-full.yaml` - Fixed notification URL
- ✅ `scripts/fix-watchtower-notifications.sh` - Safe fix script
- ✅ `docs/WATCHTOWER_SECURITY_ANALYSIS.md` - Security analysis

# Watchtower Security Analysis - CORRECTED
**Generated**: February 9, 2026
**Status**: ⚠️ **CRITICAL CORRECTION TO PREVIOUS RECOMMENDATION**
---
## 🚨 **IMPORTANT: DO NOT MAKE DOCKER SOCKET READ-ONLY**
### **❌ Previous Recommendation Was INCORRECT**
I initially recommended making the Docker socket read-only for security. **This would BREAK Watchtower completely.**
### **✅ Why Watchtower NEEDS Write Access**
Watchtower requires **full read-write access** to the Docker socket to perform its core functions:
#### **Required Docker Operations**
1. **Pull new images**: `docker pull <image>:latest`
2. **Stop containers**: `docker stop <container>`
3. **Remove old containers**: `docker rm <container>`
4. **Create new containers**: `docker create/run <new-container>`
5. **Start containers**: `docker start <container>`
6. **Remove old images**: `docker rmi <old-image>` (when cleanup=true)
#### **Current Configuration Analysis**
```bash
# Your current Watchtower config:
WATCHTOWER_HTTP_API_UPDATE=true # Updates via HTTP API only
WATCHTOWER_CLEANUP=true # Removes old images (needs write access)
WATCHTOWER_SCHEDULE=0 0 4 * * * # Daily at 4 AM (but API mode overrides)
```
---
## 🔍 **Actual Security Status: ACCEPTABLE**
### **✅ Current Security Posture is GOOD**
Your Watchtower configuration is actually **more secure** than typical setups:
#### **Security Features Already Enabled**
1. **HTTP API Mode**: Updates only triggered via authenticated API calls
2. **No Automatic Polling**: `Periodic runs are not enabled`
3. **API Token Protection**: Requires `watchtower-update-token` for updates
4. **Scoped Access**: Only monitors containers (not system-wide access)
#### **How It Works**
```bash
# Updates are triggered via API, not automatically:
curl -H "Authorization: Bearer watchtower-update-token" \
-X POST http://localhost:8091/v1/update
```
### **✅ This is SAFER than Default Watchtower**
**Default Watchtower**: Automatically updates containers on schedule
**Your Watchtower**: Only updates when explicitly triggered via API
---
## 🔧 **Actual Security Recommendations**
### **1. Current Setup is Secure ✅**
- **Keep** read-write Docker socket access (required for functionality)
- **Keep** HTTP API mode (more secure than automatic updates)
- **Keep** API token authentication
### **2. Minor Improvements Available**
#### **A. Fix Notification Protocol**
```yaml
# Change HTTPS to HTTP in notification URL
WATCHTOWER_NOTIFICATION_URL: http://192.168.0.210:8081/updates
```
#### **B. Restrict API Access (Optional)**
```yaml
# Bind API to localhost only (if not needed externally)
ports:
- "127.0.0.1:8091:8080" # Instead of "8091:8080"
```
#### **C. Use Docker Socket Proxy (Advanced)**
If you want additional security, use a Docker socket proxy:
```yaml
# tecnativa/docker-socket-proxy - filters Docker API calls
# But this is overkill for most homelab setups
```
---
## 🎯 **Corrected Action Plan**
### **❌ DO NOT DO**
- ~~Make Docker socket read-only~~ (Would break Watchtower)
- ~~Remove write permissions~~ (Would break container updates)
### **✅ SAFE ACTIONS**
1. **Fix notification URL**: Change HTTPS to HTTP
2. **Update repository configs**: Align with running container
3. **Document API usage**: How to trigger updates manually
### **✅ OPTIONAL SECURITY ENHANCEMENTS**
1. **Restrict API binding**: Localhost only if not needed externally
2. **Monitor API access**: Log API calls for security auditing
3. **Regular token rotation**: Change API token periodically
---
## 📊 **Security Comparison**
| Configuration | Security Level | Functionality | Recommendation |
|---------------|----------------|---------------|----------------|
| **Your Current Setup** | 🟢 **HIGH** | ✅ Full | ✅ **KEEP** |
| Read-only Docker socket | 🔴 **BROKEN** | ❌ None | ❌ **AVOID** |
| Default Watchtower | 🟡 **MEDIUM** | ✅ Full | 🟡 Less secure |
| With Socket Proxy | 🟢 **HIGHEST** | ✅ Full | 🟡 Complex setup |
---
## 🔍 **How to Verify Current Security**
### **Check API Mode is Active**
```bash
# Should show "Periodic runs are not enabled"
sudo docker logs watchtower --tail 20 | grep -i periodic
```
### **Test API Authentication**
```bash
# This should fail (no token)
curl -X POST http://localhost:8091/v1/update
# This should work (with token)
curl -H "Authorization: Bearer watchtower-update-token" \
-X POST http://localhost:8091/v1/update
```
### **Verify Container Updates Work**
```bash
# Trigger manual update via API
curl -H "Authorization: Bearer watchtower-update-token" \
-X POST http://localhost:8091/v1/update
```
---
## 🎉 **Conclusion**
### **✅ Your Watchtower is ALREADY SECURE**
Your current configuration is **more secure** than typical Watchtower setups because:
- Updates require explicit API calls (not automatic)
- API calls require authentication token
- No periodic polling running
### **❌ My Previous Recommendation Was WRONG**
Making the Docker socket read-only would have **completely broken** Watchtower's ability to:
- Pull new images
- Update containers
- Clean up old images
- Perform any container management
### **✅ Keep Your Current Setup**
Your Watchtower configuration strikes the right balance between **security** and **functionality**.
---
## 📝 **Updated Fix Script Status**
**⚠️ DO NOT RUN** `scripts/fix-watchtower-security.sh`
The script contains an incorrect recommendation that would break Watchtower. I'll create a corrected version that:
- Fixes the notification URL (HTTPS → HTTP)
- Updates repository configurations
- Preserves essential Docker socket access
---
*This corrected analysis supersedes the previous CONTAINER_DIAGNOSIS_REPORT.md security recommendations.*

## Configure OAuth2 Providers
### Critical: Scope Mappings
**EVERY OAuth2 provider MUST have these scope mappings configured, or logins will fail with "InternalError":**
1. Go to: Admin → Customization → Property Mappings
2. Note these default mappings exist:
- `authentik default OAuth Mapping: OpenID 'openid'`
- `authentik default OAuth Mapping: OpenID 'email'`
- `authentik default OAuth Mapping: OpenID 'profile'`
When creating providers, you MUST add these to the "Scopes" field.
### Provider 1: Grafana OAuth2
**Admin → Providers → Create → OAuth2/OpenID Provider**
| Setting | Value |
|---------|-------|
| Name | `Grafana OAuth2` |
| Authentication flow | default-authentication-flow |
| Authorization flow | default-provider-authorization-implicit-consent |
| Client type | Confidential |
| Client ID | (auto-generated, save this) |
| Client Secret | (auto-generated, save this) |
| Redirect URIs | `https://gf.vish.gg/login/generic_oauth` |
| Signing Key | authentik Self-signed Certificate |
| **Scopes** | Select: `openid`, `email`, `profile` ⚠️ CRITICAL |

## Configure Forward Auth Providers
Forward Auth is used for services that don't have native OAuth support. Authentik intercepts all requests and requires login first.
### Provider: vish.gg Domain Forward Auth
**Admin → Providers → Create → Proxy Provider**
| Setting | Value |
|---------|-------|
| Name | `vish.gg Domain Forward Auth` |
| Authorization flow | default-provider-authorization-implicit-consent |

| External host | `https://sso.vish.gg` |
**Create Application:**
- Name: `vish.gg Domain Auth`
- Slug: `vishgg-domain-auth`
- Provider: `vish.gg Domain Forward Auth`
### Create/Update Outpost
**Admin → Applications → Outposts**
1. Edit the embedded outpost (or create one)
2. Add all Forward Auth applications to it
3. The outpost will listen on port 9000
---
## Service-Specific Configuration

}
```
Then restart Seafile: `docker restart Seafile`
---
## NPM Integration
### For OAuth2 Services (Grafana, Gitea, etc.)
**DO NOT add Forward Auth config!** These services handle OAuth themselves.
NPM proxy host should be simple:
- Forward host: service IP
- Forward port: service port
- SSL: enabled
- Advanced config: **EMPTY**
### For Forward Auth Services (Paperless, Actual, etc.)
Add this to NPM Advanced Config:
```nginx
# Authentik Forward Auth Configuration
proxy_buffers 8 16k;
proxy_buffer_size 32k;
auth_request /outpost.goauthentik.io/auth/nginx;
error_page 401 = @goauthentik_proxy_signin;
auth_request_set $auth_cookie $upstream_http_set_cookie;
add_header Set-Cookie $auth_cookie;
auth_request_set $authentik_username $upstream_http_x_authentik_username;
auth_request_set $authentik_groups $upstream_http_x_authentik_groups;
auth_request_set $authentik_email $upstream_http_x_authentik_email;
auth_request_set $authentik_name $upstream_http_x_authentik_name;
auth_request_set $authentik_uid $upstream_http_x_authentik_uid;
proxy_set_header X-authentik-username $authentik_username;
proxy_set_header X-authentik-groups $authentik_groups;
proxy_set_header X-authentik-email $authentik_email;
proxy_set_header X-authentik-name $authentik_name;
proxy_set_header X-authentik-uid $authentik_uid;
location /outpost.goauthentik.io {
proxy_pass http://192.168.0.250:9000/outpost.goauthentik.io;
proxy_set_header Host $host;
proxy_set_header X-Original-URL $scheme://$http_host$request_uri;
add_header Set-Cookie $auth_cookie;
auth_request_set $auth_cookie $upstream_http_set_cookie;
proxy_pass_request_body off;
proxy_set_header Content-Length "";
}
location @goauthentik_proxy_signin {
internal;
add_header Set-Cookie $auth_cookie;
return 302 https://sso.vish.gg/outpost.goauthentik.io/start?rd=$scheme://$http_host$request_uri;
}
```
### Services with Forward Auth Configured
| Domain | Backend | Port |
|--------|---------|------|
| paperless.vish.gg | 192.168.0.250 | 8777 |
| docs.vish.gg | 192.168.0.250 | 8777 |
| actual.vish.gg | 192.168.0.250 | 8304 |
| npm.vish.gg | 192.168.0.250 | 81 |
---
## Troubleshooting
### "InternalError" After OAuth Login
**Root Cause**: Missing scope mappings in Authentik provider.
**Fix**:
1. Admin → Providers → Edit the OAuth2 provider
2. Scroll to "Scopes" section
3. Add: `openid`, `email`, `profile`
4. Save
**Verify**:
```bash
curl https://sso.vish.gg/application/o/<app-slug>/.well-known/openid-configuration | jq '.scopes_supported'
```
### Redirect Loop Between Service and Authentik
**Root Cause**: Forward Auth configured in NPM for a service that uses native OAuth.
**Fix**:
1. NPM → Proxy Hosts → Edit the affected host
2. Go to Advanced tab
3. **Clear all content** from the Advanced Config box
4. Save
### "User not found" or "No email" Errors
**Root Cause**: Missing attribute paths in service config.
**Fix for Grafana**:
```
GF_AUTH_GENERIC_OAUTH_EMAIL_ATTRIBUTE_PATH=email
GF_AUTH_GENERIC_OAUTH_LOGIN_ATTRIBUTE_PATH=preferred_username
```
### OAuth Works But User Gets Wrong Permissions
**Root Cause**: Missing group claim or incorrect role mapping.
**Fix**:
1. Ensure user is in correct Authentik group
2. Verify `groups` scope is included
3. Check role mapping expression in service config
### Can't Access Authentik Admin
**Create recovery token via Portainer or SSH**:
```bash
docker exec -it Authentik-SERVER ak create_recovery_key 10 akadmin
```
This generates a one-time URL valid for 10 minutes.
---
## Recovery Procedures
### Scenario: Complete Authentik Loss
1. **Restore from backup** (if available):
```bash
# Restore PostgreSQL database
docker exec -i Authentik-DB psql -U authentik authentik < backup.sql
# Restore media files
rsync -av backup/media/ /volume1/docker/authentik/media/
```
2. **Or redeploy from scratch**:
- Follow this entire guide from [Deploy Authentik](#deploy-authentik)
- You'll need to reconfigure all OAuth providers
- Services will need their OAuth credentials updated
### Scenario: Locked Out of Admin
```bash
# Via SSH to Calypso or Portainer exec
docker exec -it Authentik-SERVER ak create_recovery_key 10 akadmin
```
Navigate to the URL it outputs.
### Scenario: Service OAuth Broken After Authentik Rebuild
1. Create new OAuth2 provider in Authentik (same settings)
2. Note new Client ID and Secret
3. Update service configuration with new credentials
4. Restart service
5. Test login
### Scenario: Forward Auth Not Working
1. Verify Authentik outpost is running:
```bash
docker logs Authentik-SERVER | grep -i outpost
```
2. Verify outpost includes the application:
- Admin → Outposts → Edit → Check application is selected
3. Test outpost endpoint:
```bash
curl -I http://192.168.0.250:9000/outpost.goauthentik.io/ping
```
4. Check NPM Advanced Config has correct Authentik IP

### Service Status Checklist
After rebuilding, verify each service:
```bash
# OAuth2 Services
curl -sI https://gf.vish.gg | head -1 # Should be 302
curl -sI https://git.vish.gg | head -1 # Should be 200
curl -sI https://sf.vish.gg | head -1 # Should be 302
# Forward Auth Services
curl -sI https://paperless.vish.gg | head -1 # Should be 302 to SSO
curl -sI https://actual.vish.gg | head -1 # Should be 302 to SSO
# Authentik itself
curl -sI https://sso.vish.gg | head -1 # Should be 302
```

```
### 🛠️ **Router Replacement Procedure**
#### **Step 1: Physical Setup**
```bash
# 1. Connect new router to modem
# 2. Connect computer directly to router via Ethernet
# 3. Power on router and wait for boot (2-3 minutes)
```
#### **Step 2: Basic Network Configuration**
```bash
# Access router admin interface
# Default is usually: http://192.168.1.1 or http://192.168.0.1
# For TP-Link Archer BE800 v1.6: http://192.168.0.1 or http://tplinkwifi.net
# Default login: admin/admin
# If different subnet, find router IP:
ip route | grep default
# or
arp -a | grep -E "(router|gateway)"
```
**Router Configuration Checklist:**
```bash
# ✅ Set admin password (use password manager)
# ✅ Configure WAN connection (DHCP/Static/PPPoE)
# ✅ Set WiFi SSID and password
# ✅ Configure subnet: 192.168.1.0/24
# ✅ Set DHCP range: 192.168.1.100-192.168.1.200
# ✅ Configure DNS servers: 1.1.1.1, 8.8.8.8
# ✅ Enable UPnP (if needed)
# ✅ Disable WPS (security)
```
**📖 For TP-Link Archer BE800 v1.6 specific instructions, see: [TP-Link Archer BE800 Setup Guide](../infrastructure/tplink-archer-be800-setup.md)**
#### **Step 3: Static IP Assignment**
**Critical Static IPs (Configure First):**
```bash
# In router DHCP reservation settings:
# Primary Infrastructure
atlantis.vish.local → 192.168.1.100 # MAC: [Document MAC]
calypso.vish.local → 192.168.1.101 # MAC: [Document MAC]
concord-nuc.vish.local → 192.168.1.102 # MAC: [Document MAC]
# Virtual Machines
homelab-vm.vish.local → 192.168.1.103 # MAC: [Document MAC]
chicago-vm.vish.local → 192.168.1.104 # MAC: [Document MAC]
bulgaria-vm.vish.local → 192.168.1.105 # MAC: [Document MAC]
# Specialized Hosts
anubis.vish.local → 192.168.1.106 # MAC: [Document MAC]
guava.vish.local → 192.168.1.107 # MAC: [Document MAC]
setillo.vish.local → 192.168.1.108 # MAC: [Document MAC]
# Raspberry Pi Cluster
rpi-vish.vish.local → 192.168.1.109 # MAC: [Document MAC]
rpi-kevin.vish.local → 192.168.1.110 # MAC: [Document MAC]
# Edge Devices
nvidia-shield.vish.local → 192.168.1.111 # MAC: [Document MAC]
```
**Find MAC Addresses:**
```bash
# On each host, run:
ip link show | grep -E "(ether|link)"
# or
cat /sys/class/net/eth0/address
# From router, check DHCP client list
# Or use network scanner:
nmap -sn 192.168.1.0/24
arp -a
```
#### **Step 4: Port Forwarding Configuration**
**Essential Port Forwards (Configure Immediately):**
```bash
# VPN Access (Highest Priority)
External: 51820/UDP → Internal: 192.168.1.100:51820 (Atlantis WireGuard)
External: 51821/UDP → Internal: 192.168.1.102:51820 (Concord WireGuard)
# Web Services (If needed)
External: 80/TCP → Internal: 192.168.1.100:8341 (HTTP)
External: 443/TCP → Internal: 192.168.1.100:8766 (HTTPS)
```
**Gaming Services (If hosting public games):**
```bash
# Satisfactory Server
External: 7777/TCP → Internal: 192.168.1.103:7777
External: 7777/UDP → Internal: 192.168.1.103:7777
# Left 4 Dead 2 Server
External: 27015/TCP → Internal: 192.168.1.103:27015
External: 27015/UDP → Internal: 192.168.1.103:27015
External: 27020/UDP → Internal: 192.168.1.103:27020
External: 27005/UDP → Internal: 192.168.1.103:27005
```
#### **Step 5: Dynamic DNS Configuration**
**Update DDNS Settings:**
```bash
# Method 1: Router Built-in DDNS
# Configure in router: Advanced → Dynamic DNS
# Service: [Your provider]
# Hostname: vishinator.synology.me
# Username: [Your DDNS username]
# Password: "REDACTED_PASSWORD" DDNS password]
# Method 2: Manual Update (if router doesn't support your provider)
# SSH to a homelab host and run:
curl -u "username:password" \
"https://your-ddns-provider.com/update?hostname=vishinator.synology.me&myip=$(curl -s ifconfig.me)"
```
**Test DDNS:**
```bash
# Wait 5-10 minutes, then test:
nslookup vishinator.synology.me
dig vishinator.synology.me
# Should return your new external IP
curl ifconfig.me # Compare with DDNS result
```
### 🔧 **Service Recovery Order**
**Phase 1: Core Infrastructure (First 30 minutes)**
```bash
# 1. Verify network connectivity
ping 8.8.8.8
ping google.com
# 2. Check all hosts are reachable
ping atlantis.vish.local
ping calypso.vish.local
ping concord-nuc.vish.local
# 3. Verify DNS resolution
nslookup atlantis.vish.local
```
**Phase 2: Essential Services (Next 30 minutes)**
```bash
# 4. Check VPN services
# Test WireGuard from external device
# Verify Tailscale connectivity
# 5. Verify password manager
curl -I https://atlantis.vish.local:8222 # Vaultwarden
# 6. Check monitoring

```bash
# 1. Connect phone to new router WiFi
# 2. Enable mobile hotspot on another device
# 3. Connect computer to mobile hotspot
# 4. Access router via: http://192.168.1.1
# 5. Configure WAN settings to use mobile hotspot temporarily
```
---
## 🌐 Network Reconfiguration Scenarios
### **ISP Changes (New Modem/Different Settings)**
#### **Scenario 1: New Cable Modem**
```bash
# 1. Connect new modem to router WAN port
# 2. Power cycle both devices (modem first, then router)
# 3. Check WAN connection in router interface
# 4. Update DDNS if external IP changed
# 5. Test port forwarding from external network
```
#### **Scenario 2: Fiber Installation**
```bash
# 1. Configure router for new connection type
# 2. May need PPPoE credentials from ISP
# 3. Update MTU settings if required (usually 1500 for fiber)
# 4. Test speed and latency
# 5. Update monitoring dashboards with new metrics
```
#### **Scenario 3: Subnet Change Required**
```bash
# If you need to change from 192.168.1.x to different subnet:
# 1. Plan new IP scheme
# Old: 192.168.1.0/24
# New: 192.168.2.0/24 (example)
# 2. Update router DHCP settings
# 3. Update static IP reservations
# 4. Update all service configurations
# 5. Update Tailscale subnet routes
# 6. Update monitoring configurations
# 7. Update documentation
```
### **IP Conflict Resolution**
```bash
# If new router uses different default subnet:
# 1. Identify conflicts
nmap -sn 192.168.0.0/24 # Scan new subnet
nmap -sn 192.168.1.0/24 # Scan old subnet
# 2. Choose resolution strategy:
# Option A: Change router to use 192.168.1.x
# Option B: Reconfigure all devices for new subnet
# 3. Update all static configurations
# 4. Update firewall rules
# 5. Update service discovery
```
---
## 🔌 Power Outage Recovery
### **Startup Sequence (Critical Order)**
```bash
# Phase 1: Infrastructure (0-5 minutes)
# 1. Modem/Internet connection
# 2. Router/Switch
# 3. NAS devices (Atlantis, Calypso) - these take longest to boot
# Phase 2: Core Services (5-10 minutes)
# 4. Primary compute hosts (concord-nuc)
# 5. Virtual machine hosts
# Phase 3: Applications (10-15 minutes)
# 6. Raspberry Pi devices
# 7. Edge devices
# 8. Verify all services are running
```
**Automated Startup Script:**
```bash
#!/bin/bash
# ~/homelab-recovery/startup-sequence.sh
echo "🔌 Starting homelab recovery sequence..."
# Wait for network
echo "⏳ Waiting for network connectivity..."
while ! ping -c 1 8.8.8.8 >/dev/null 2>&1; do
sleep 5
done
echo "✅ Network is up"
# Check each host
hosts=(
"atlantis.vish.local"
"calypso.vish.local"
"concord-nuc.vish.local"
"homelab-vm.vish.local"
"chicago-vm.vish.local"
"bulgaria-vm.vish.local"
)
for host in "${hosts[@]}"; do
echo "🔍 Checking $host..."
if ping -c 1 "$host" >/dev/null 2>&1; then
echo "✅ $host is responding"
else
echo "❌ $host is not responding"
fi
done
echo "🎯 Recovery sequence complete"
```
---
## 💾 Storage Failure Recovery
### **Backup Verification**
```bash
# Before disaster strikes, verify backups exist:
# 1. Docker volume backups
ls -la /volume1/docker/*/
du -sh /volume1/docker/*/
# 2. Configuration backups
find ~/homelab-recovery -name "*.yml" -o -name "*.yaml"
# 3. Database backups
ls -la /volume1/docker/*/backup/
ls -la /volume1/docker/*/db_backup/
```
### **Service Restoration Priority**
```bash
# 1. Password Manager (Vaultwarden) - Need passwords for everything else
# 2. DNS/DHCP (Pi-hole) - Network services
# 3. Monitoring (Grafana/Prometheus) - Visibility into recovery
# 4. VPN (WireGuard/Tailscale) - Remote access
# 5. Media services - Lower priority
# 6. Development services - Lowest priority
```

# Emergency Procedures
This document outlines emergency procedures for critical failures in the homelab infrastructure.
## 🚨 Emergency Contact Information
### Critical Service Access
- **Vaultwarden Emergency**: See [Offline Password Access](offline-password-access.md)
- **Network Emergency**: Router admin at `192.168.0.1` (admin/admin)
- **Power Emergency**: UPS management at `192.168.0.50`
### External Services
- **Cloudflare**: Dashboard access for DNS/tunnel management
- **Tailscale**: Admin console for mesh VPN recovery
- **Domain Registrar**: For DNS changes if Cloudflare fails
## 🔥 Critical Failure Scenarios
### Complete Network Failure
#### Symptoms
- No internet connectivity
- Cannot access local services
- Router/switch unresponsive
#### Immediate Actions
1. **Check Physical Connections**
```bash
# Check cable connections
# Verify power to router/switches
# Check UPS status
```
2. **Router Recovery**
```bash
# Power cycle router (30-second wait)
# Access router admin: http://192.168.0.1
# Check WAN connection status
# Verify DHCP is enabled
```
3. **Switch Recovery**
```bash
# Power cycle managed switches
# Check link lights on all ports
# Verify VLAN configuration if applicable
```
#### Recovery Steps
1. Restore basic internet connectivity
2. Verify internal network communication
3. Restart critical services in order (see [Service Dependencies](../services/dependencies.md))
4. Test external access through port forwards
### Power Outage Recovery
#### During Outage
- UPS should maintain critical systems for 15-30 minutes
- Graceful shutdown sequence will be triggered automatically
- Monitor UPS status via web interface if accessible
#### After Power Restoration
1. **Wait for Network Stability** (5 minutes)
2. **Start Core Infrastructure**
```bash
# Synology NAS systems (auto-start enabled)
# Router and switches (auto-start)
# Internet connection verification
```
3. **Start Host Systems in Order**
- Proxmox hosts
- Physical machines (Anubis, Guava, Concord NUC)
- Raspberry Pi devices
4. **Verify Service Health**
```bash
# Check Portainer endpoints
# Verify monitoring stack
# Test critical services (Plex, Vaultwarden, etc.)
```
### Storage System Failure
#### Synology NAS Failure
```bash
# Check RAID status
cat /proc/mdstat
# Check disk health
smartctl -a /dev/sda
# Emergency data recovery
# 1. Stop all Docker containers
# 2. Mount drives on another system
# 3. Copy critical data
# 4. Restore from backups
```
#### Critical Data Recovery Priority
1. **Vaultwarden database** - Password access
2. **Configuration files** - Service configs
3. **Media libraries** - Plex/Jellyfin content
4. **Personal data** - Photos, documents
### Authentication System Failure (Authentik)
#### Symptoms
- Cannot log into SSO-protected services
- Grafana, Portainer access denied
- Web services show authentication errors
#### Emergency Access
1. **Use Local Admin Accounts**
```bash
# Portainer: Use local admin account
# Grafana: Use admin/admin fallback
# Direct service access via IP:port
```
2. **Bypass Authentication Temporarily**
```bash
# Edit compose files to disable auth
# Restart services without SSO
# Fix Authentik issues
# Re-enable authentication
```
### Database Corruption
#### PostgreSQL Recovery
```bash
# Stop all dependent services
docker stop service1 service2
# Backup corrupted database
docker exec postgres pg_dump -U user database > backup.sql
# Restore from backup
docker exec -i postgres psql -U user database < clean_backup.sql
# Restart services
docker start service1 service2
```
#### Redis Recovery
```bash
# Stop Redis
docker stop redis
# Check data integrity
docker run --rm -v redis_data:/data redis redis-check-rdb /data/dump.rdb
# Restore from backup or start fresh
docker start redis
```
## 🛠️ Emergency Toolkit
### Essential Commands
```bash
# System status overview
htop && df -h && docker ps
# Network connectivity test
ping 8.8.8.8 && ping google.com
# Service restart (replace service-name)
docker restart service-name
# Emergency container stop
docker stop $(docker ps -q)
# Emergency system reboot
sudo reboot
```
### Emergency Access Methods
#### SSH Access
```bash

# Guava SMB Incident — 2026-03-14
**Affected host:** guava (TrueNAS SCALE, `100.75.252.64` / `192.168.0.100`)
**Affected client:** shinku-ryuu (Windows, `192.168.0.3`)
**Symptoms:** All SMB shares on guava unreachable from shinku after guava reboot
---
## Root Causes (two separate issues)
### 1. Tailscale app was STOPPED after reboot
Guava's Tailscale was running as an **orphaned host process** rather than the managed TrueNAS app. On reboot the orphan was gone and the app didn't start because it was in `STOPPED` state.
**Why it was stopped:** The app had been upgraded from v1.3.30 → v1.4.2. The new version's startup script ran `tailscale up` but failed because the stored state had `--accept-dns=false` while the app config had `accept_dns: true` — a mismatch that requires `--reset`. The app exited, leaving the old manually-started daemon running until the next reboot.
### 2. Tailscale `accept_routes: true` caused SMB replies to route via tunnel
After fixing the app startup, shinku still couldn't reach guava on the LAN. The cause:
- **Calypso** advertises `192.168.0.0/24` as a subnet route via Tailscale
- Guava had `accept_routes: true` — it installed Calypso's `192.168.0.0/24` route into Tailscale's policy routing table (table 52, priority 5270)
- When shinku sent a TCP SYN to guava port 445, it arrived on `enp1s0f0np0`
- Guava's reply looked up `192.168.0.3` in the routing table — hit table 52 first — and sent the reply **out via `tailscale0`** instead of the LAN
- The reply never reached shinku; the connection timed out
This also affected shinku: it had `accept_routes: true` as well, so it was routing traffic destined for `192.168.0.100` via Calypso's Tailscale tunnel rather than its local Ethernet interface.
---
## Fixes Applied
### Fix 1 — Tailscale app startup config
Updated the TrueNAS app config to match the node's actual desired state:
```bash
sudo midclt call app.update tailscale '{"values": {"tailscale": {
"accept_dns": false,
"accept_routes": false,
"advertise_exit_node": true,
"advertise_routes": [],
"auth_key": "...",
"auth_once": true,
"hostname": "truenas-scale",
"reset": true
}}}'
```
Key changes:
- `accept_dns: false` — matches the running state stored in Tailscale's state dir
- `accept_routes: false` — prevents guava from pulling in subnet routes from other nodes (see Fix 2)
- `reset: true` — clears the flag mismatch that was causing `tailscale up` to fail
**Saved in:** `/mnt/.ix-apps/app_configs/tailscale/versions/1.4.2/user_config.yaml`
### Fix 2 — Remove stale subnet routes from guava's routing table
After updating the app config the stale routes persisted in table 52. Removed manually:
```bash
sudo ip route del 192.168.0.0/24 dev tailscale0 table 52
sudo ip route del 192.168.12.0/24 dev tailscale0 table 52
sudo ip route del 192.168.68.0/22 dev tailscale0 table 52
sudo ip route del 192.168.69.0/24 dev tailscale0 table 52
```
With `accept_routes: false` now saved, these routes will not reappear on next reboot.
### Fix 3 — Disable accept_routes on shinku
Shinku was also accepting Calypso's `192.168.0.0/24` route (metric 0 via Tailscale, beating Ethernet 3's metric 256):
```
# Before fix — traffic to 192.168.0.100 went via Tailscale
192.168.0.0/24 100.100.100.100 0 Tailscale
# After fix — traffic goes via local LAN
192.168.0.0/24 0.0.0.0 256 Ethernet 3
```
Fixed by running on shinku:
```
tailscale up --accept-routes=false --login-server=https://headscale.vish.gg:8443
```
### Fix 4 — SMB password reset and credential cache
The SMB password for `vish` on guava was changed via the TrueNAS web UI. Windows had stale credentials cached. Fixed by:
1. Clearing Windows Credential Manager entry for `192.168.0.100`
2. Re-mapping shares from an interactive PowerShell session on shinku
---
## SMB Share Layout on Guava
| Windows drive | Share | Path on guava |
|--------------|-------|---------------|
| I: | `guava_turquoise` | `/mnt/data/guava_turquoise` |
| J: | `photos` | `/mnt/data/photos` |
| K: | `data` | `/mnt/data/passionfruit` |
| L: | `website` | `/mnt/data/website` |
| M: | `jellyfin` | `/mnt/data/jellyfin` |
| N: | `truenas-exporters` | `/mnt/data/truenas-exporters` |
| Q: | `iso` | `/mnt/data/iso` |
All shares use `vish` as the SMB user. Credentials stored in Windows Credential Manager under `192.168.0.100`.
---
## Diagnosis Commands
```bash
# Check Tailscale app state on guava
ssh guava "sudo midclt call app.query '[[\"name\",\"=\",\"tailscale\"]]' | python3 -c 'import sys,json; a=json.load(sys.stdin)[0]; print(a[\"name\"], a[\"state\"])'"
# Check for rogue subnet routes in Tailscale's routing table
ssh guava "ip route show table 52 | grep 192.168"
# Check tailscale container logs
ssh guava "sudo docker logs \$(sudo docker ps | grep tailscale | awk '{print \$1}' | head -1) 2>&1 | tail -20"
# Check SMB audit log for auth failures on guava
ssh guava "sudo journalctl -u smbd --since '1 hour ago' --no-pager | grep -i 'wrong_password\|STATUS'"
# Check which Tailscale peer is advertising a given subnet (run on any node)
tailscale status --json | python3 -c "
import sys, json
d = json.load(sys.stdin)
for peer in d.get('Peer', {}).values():
routes = peer.get('PrimaryRoutes') or []
if routes:
print(peer['HostName'], routes)
"
```
---
## Prevention
- **Guava:** `accept_routes: false` is now saved in the TrueNAS app config — will survive reboots
- **Shinku:** `--accept-routes=false` set via `tailscale up` — survives reboots
- **General rule:** Hosts on the same LAN as the subnet-advertising node (Calypso → `192.168.0.0/24`) should have `accept_routes: false`, or the advertised subnet should be scoped to only nodes that need remote access to that LAN
- **TrueNAS app upgrades:** After upgrading the Tailscale app version, always check the new `user_config.yaml` to ensure `accept_dns`, `accept_routes`, and other flags match the node's actual running state. If unsure, set `reset: true` once to clear any stale state, then set it back to `false`

# Accessing the Homelab During an Internet Outage
**When your internet goes down, the homelab keeps running.** This guide covers exactly how to reach each service via LAN or Tailscale (which uses peer-to-peer WireGuard — it continues working between nodes that already have keys exchanged, even without the coordination server).
---
## Quick Reference — What Still Works
| Category | Services | Access Method |
|----------|----------|---------------|
| **Streaming** | Plex, Jellyfin, Audiobookshelf | LAN IP or Tailscale IP |
| **Media mgmt** | Sonarr, Radarr, SABnzbd, Prowlarr | LAN IP or Tailscale IP |
| **Photos** | Immich (Atlantis + Calypso) | LAN IP or Tailscale IP |
| **Documents** | Paperless-NGX | LAN IP or Tailscale IP |
| **Passwords** | Vaultwarden | LAN IP or Tailscale IP |
| **Files** | Seafile, Syncthing | LAN IP or Tailscale IP |
| **Notes** | Joplin, BookStack | LAN IP or Tailscale IP |
| **Git/CI** | Gitea, Portainer | LAN IP or Tailscale IP |
| **Monitoring** | Grafana, Prometheus, Uptime Kuma | LAN IP or Tailscale IP |
| **Home Auto** | Home Assistant | LAN IP or Tailscale IP |
| **Dashboard** | Homarr | LAN IP or Tailscale IP |
| **Finance** | Actual Budget | LAN IP or Tailscale IP |
| **Comms** | Mattermost, Matrix (local rooms) | LAN IP or Tailscale IP |
| **Auth** | Authentik SSO | LAN IP or Tailscale IP (fully local) |
**What does NOT work without internet:**
- New downloads (Sonarr/Radarr can't search indexers, SABnzbd can't download)
- Invidious, Piped, Redlib (they ARE the internet)
- YourSpotify, ProtonMail Bridge
- External access via `*.vish.gg` domains (Cloudflare proxy down)
- iOS push notifications via ntfy (ntfy.sh upstream unavailable)
- AI tagging in Hoarder (OpenAI API)

## Access Methods
### Method 1 — LAN (same network as Atlantis/Calypso)
You must be physically connected to the home network (Ethernet or WiFi).
| Host | LAN IP | Notes |
|------|--------|-------|
| Atlantis | `192.168.0.200` | Primary NAS — most services |
| Calypso | `192.168.0.250` | Secondary NAS — Gitea, Authentik, Paperless, Immich |
| Homelab VM | `192.168.0.X` | Check router DHCP — runs monitoring, Mattermost |
| Concord NUC | `192.168.0.X` | Check router DHCP |
| Pi-5 | `192.168.0.66` | Uptime Kuma, Glances |
| Guava (TrueNAS) | `192.168.0.100` | NAS shares |
| Home Assistant | `192.168.12.202` (behind MT3000) | HA Green |
### Method 2 — Tailscale / Headscale (any network, any location)
Tailscale uses WireGuard peer-to-peer. **Once nodes have exchanged keys, they communicate directly without needing the coordination server (headscale on Calypso).** An internet outage does not break existing Tailscale sessions.
| Host | Tailscale IP | SSH Alias |
|------|-------------|-----------|
| Atlantis | `100.83.230.112` | `atlantis` |
| Calypso | `100.103.48.78` | `calypso` |
| Homelab VM | `100.67.40.126` | `homelab-vm` |
| Concord NUC | `100.72.55.21` | `nuc` |
| Pi-5 | `100.77.151.40` | `pi-5` |
| Guava | `100.75.252.64` | `guava` |
| Moon | `100.64.0.6` | `moon` |
| Setillo | `100.125.0.20` | `setillo` |
| Seattle VPS | `100.82.197.124` | `seattle-tailscale` |
**MagicDNS** also works on Tailscale: `atlantis.tail.vish.gg`, `calypso.tail.vish.gg`, etc.
> **Note:** If headscale itself needs to restart during an outage, it will now start fine (fixed 2026-03-16 — `only_start_if_oidc_is_available: false`). Existing node sessions survive a headscale restart indefinitely.

## SSH Access During Outage
All hosts have SSH key-based auth. From any machine on LAN or Tailscale:
```bash
# Atlantis (Synology DSM)
ssh -p 60000 vish@192.168.0.200 # LAN
ssh atlantis # Tailscale (uses ~/.ssh/config)
# Calypso (Synology DSM)
ssh -p 62000 Vish@192.168.0.250 # LAN (capital V)
ssh calypso # Tailscale
# Homelab VM
ssh homelab@100.67.40.126 # Tailscale only (no LAN port forward)
# Concord NUC
ssh nuc # Tailscale
# Pi-5
ssh pi-5 # Tailscale (vish@100.77.151.40)
# Guava (TrueNAS)
ssh vish@192.168.0.100 # LAN
ssh guava # Tailscale
# Moon (remote)
ssh moon # Tailscale only (100.64.0.6)
```
---
## NPM / Reverse Proxy
NPM runs on Calypso (`192.168.0.250`, port 81 admin UI). During an internet outage, NPM itself keeps running and continues to proxy internal traffic. SSL certs remain valid for up to 90 days — cert renewal requires internet (Let's Encrypt + Cloudflare DNS).
For LAN access you don't go through NPM at all — use the direct host:port addresses above.
---
## Tailscale Not Working?
If Tailscale connectivity is lost during an outage:
1. **Check if headscale is up on Calypso:**
```bash
ssh -p 62000 Vish@192.168.0.250 "sudo /usr/local/bin/docker ps | grep headscale"
```
2. **Restart headscale if needed** (it will start even without internet now):
```bash
ssh -p 62000 Vish@192.168.0.250 "sudo /usr/local/bin/docker restart headscale"
```
3. **Force re-auth on a node:**
```bash
sudo tailscale up --login-server=https://headscale.vish.gg:8443
# headscale.vish.gg resolves via LAN since it's unproxied (direct home IP)
```
4. **If headscale.vish.gg DNS fails** (DDNS not updated yet), use the direct IP:
```bash
sudo tailscale up --login-server=http://192.168.0.250:8080
```
---
## DDNS / External Access Recovery
When internet comes back after an outage, DDNS updaters on Atlantis automatically update Cloudflare within ~5 minutes. No manual action needed.
If your external IP changed during the outage and you need to update manually:
```bash
# Check current external IP
curl https://ipv4.icanhazip.com
# Check what Cloudflare has for a domain
dig +short headscale.vish.gg A
# If they differ, restart the DDNS updater on Atlantis to force immediate update
ssh atlantis "sudo /var/packages/REDACTED_APP_PASSWORD/usr/bin/docker restart \
dyndns-updater-stack-ddns-vish-unproxied-1 \
dyndns-updater-stack-ddns-vish-proxied-1 \
dyndns-updater-stack-ddns-thevish-proxied-1 \
dyndns-updater-stack-ddns-thevish-unproxied-1"
```

# Matrix SSL + Authentik + Portainer OAuth Incidents — 2026-03-19/21
---
## Issues Addressed
### 1. mx.vish.gg "Not Secure" Warning
**Symptom:** Browser showed "Not Secure" on `https://mx.vish.gg`.
**Root cause:** NPM was serving the **Cloudflare Origin Certificate** (cert ID 1, `*.vish.gg`) for `mx.vish.gg`. Cloudflare Origin certs are only trusted by Cloudflare's edge — since `mx.vish.gg` is **unproxied** (required for Matrix federation), browsers hit the origin directly and don't trust the cert.
**Fix:**
1. Got a proper Let's Encrypt cert for `mx.vish.gg` via Cloudflare DNS challenge on matrix-ubuntu:
```bash
sudo certbot certonly --dns-cloudflare \
--dns-cloudflare-credentials /etc/cloudflare.ini \
-d mx.vish.gg --email your-email@example.com --agree-tos
```
2. Copied cert to NPM as `npm-6`:
```
/volume1/docker/nginx-proxy-manager/data/custom_ssl/npm-6/fullchain.pem
/volume1/docker/nginx-proxy-manager/data/custom_ssl/npm-6/privkey.pem
```
3. Updated NPM proxy host 10 (`mx.vish.gg`) to use cert ID 6
4. Set up renewal hook: `/etc/letsencrypt/renewal-hooks/deploy/copy-to-npm.sh`
**Same fix applied for:** `livekit.mx.vish.gg` (cert `npm-7`, proxy host 47)
---
### 2. kuma.vish.gg Redirect Loop (`ERR_TOO_MANY_REDIRECTS`)
**Symptom:** `kuma.vish.gg` (Uptime Kuma) caused infinite redirect loop via Authentik Forward Auth.
**Root cause (two issues):**
**Issue A — Missing `X-Original-URL` header:**
The Authentik outpost returned `500` for Forward Auth requests because NPM wasn't passing the `X-Original-URL` header. The outpost log showed:
```
failed to detect a forward URL from nginx
```
**Fix:** Added to NPM advanced config for `kuma.vish.gg` (proxy host 41):
```nginx
auth_request /outpost.goauthentik.io/auth/nginx;
proxy_set_header X-Original-URL $scheme://$http_host$request_uri;
```
**Issue B — Empty `cookie_domain` on all Forward Auth providers:**
After login, Authentik couldn't set the session cookie correctly because `cookie_domain` was empty on all proxy providers. This caused the auth loop to continue even after successful authentication.
**Fix:** Set `cookie_domain: vish.gg` on all proxy providers via Authentik API:
| PK | Provider | Was | Now |
|----|----------|-----|-----|
| 4 | Paperless Forward Auth | `''` | `vish.gg` |
| 5 | vish.gg Domain Forward Auth | `vish.gg` | ✅ already set |
| 8 | Scrutiny Forward Auth | `''` | `vish.gg` |
| 12 | Uptime Kuma Forward Auth | `''` | `vish.gg` |
| 13 | Ollama Forward Auth | `''` | `vish.gg` |
| 14 | Wizarr Forward Auth | `''` | `vish.gg` |
```bash
AK_TOKEN="..."
for pk in 4 8 12 13 14; do
PROVIDER=$(curl -s "https://sso.vish.gg/api/v3/providers/proxy/$pk/" -H "Authorization: Bearer $AK_TOKEN")
UPDATED=$(echo "$PROVIDER" | python3 -c "import sys,json; d=json.load(sys.stdin); d['cookie_domain']='vish.gg'; print(json.dumps(d))")
curl -s -X PUT "https://sso.vish.gg/api/v3/providers/proxy/$pk/" \
-H "Authorization: Bearer $AK_TOKEN" -H "Content-Type: application/json" -d "$UPDATED"
done
```
---
### 3. TURN Server External Verification
**coturn** was verified working externally from Seattle VPS (different network):
| Test | Result |
|------|--------|
| UDP port 3479 reachable | ✅ |
| STUN Binding request | ✅ `0x0101` success, returns `184.23.52.14:3479` |
| TURN Allocate (auth required) | ✅ `0x0113` (401) — server responds, relay functional |
Config: `/etc/turnserver.conf` on matrix-ubuntu
- `listening-port=3479`
- `use-auth-secret`
- `static-auth-secret` = same as `turn_shared_secret` in Synapse homeserver.yaml
- `realm=matrix.thevish.io`
---
## NPM Certificate Reference
| Cert ID | Nice Name | Domain | Type | Expires | Notes |
|---------|-----------|--------|------|---------|-------|
| 1 | Cloudflare Origin - vish.gg | `*.vish.gg`, `vish.gg` | Cloudflare Origin | 2041 | Only trusted by CF edge — don't use for unproxied |
| 2 | Cloudflare Origin - thevish.io | `*.thevish.io` | Cloudflare Origin | 2026 | Same caveat |
| 3 | Cloudflare Origin - crista.love | `*.crista.love` | Cloudflare Origin | 2026 | Same caveat |
| 4 | git.vish.gg (LE) | `git.vish.gg` | Let's Encrypt | 2026-05 | |
| 5 | headscale.vish.gg (LE) | `headscale.vish.gg` | Let's Encrypt | 2026-06 | |
| 6 | mx.vish.gg (LE) | `mx.vish.gg` | Let's Encrypt | 2026-06 | Added 2026-03-19 |
| 7 | livekit.mx.vish.gg (LE) | `livekit.mx.vish.gg` | Let's Encrypt | 2026-06 | Added 2026-03-19 |
> **Rule:** Any domain that is **unproxied** in Cloudflare (DNS-only, orange cloud off) must use a real Let's Encrypt cert, not the Cloudflare Origin cert.
---
## Renewal Automation
Certs 6 and 7 are issued by certbot on `matrix-ubuntu` and auto-renewed via systemd timer. Deploy hooks copy renewed certs to NPM on Calypso:
```
/etc/letsencrypt/renewal-hooks/deploy/copy-to-npm.sh
```
To manually renew and deploy:
```bash
ssh matrix-ubuntu
sudo certbot renew --force-renewal -d mx.vish.gg
# hook runs automatically and copies to NPM
```
---
## Issue 4 — Portainer OAuth Hanging (2026-03-21)
**Symptom:** Clicking "Sign in with SSO" on `https://pt.vish.gg` would redirect to Authentik, authenticate successfully, but then hang on `https://pt.vish.gg/?code=...&state=...#!/auth`.
**Root causes (three layered issues):**
### A — NPM migrated to matrix-ubuntu (missed in session context)
NPM was migrated from Calypso to matrix-ubuntu (`192.168.0.154`) on 2026-03-20. All cert and proxy operations needed to target the new NPM instance.
### B — AdGuard wildcard DNS `*.vish.gg → 100.85.21.51` (matrix-ubuntu Tailscale IP)
The Calypso AdGuard had a wildcard rewrite `*.vish.gg → 100.85.21.51` (matrix-ubuntu's Tailscale IP) intended for LAN clients. This caused:
- `pt.vish.gg` → `100.85.21.51` — Portainer OAuth redirect went to matrix-ubuntu instead of Atlantis
- `sso.vish.gg` → `100.85.21.51` — Portainer's token exchange request to Authentik timed out
- `git.vish.gg` → `100.85.21.51` — Portainer GitOps stack polling timed out
**Fix:** Added specific overrides before the wildcard in AdGuard (`/opt/adguardhome/conf/AdGuardHome.yaml`):
```yaml
- domain: pt.vish.gg
answer: 192.168.0.154 # NPM on matrix-ubuntu (proxies to Atlantis:10000)
enabled: true
- domain: sso.vish.gg
answer: 192.168.0.154 # NPM on matrix-ubuntu (proxies to Authentik)
enabled: true
- domain: git.vish.gg
answer: 192.168.0.154 # NPM on matrix-ubuntu (proxies to Gitea)
enabled: true
- domain: '*.vish.gg'
answer: 100.85.21.51 # wildcard — matrix-ubuntu for everything else
```
### C — Cloudflare Origin certs not trusted by Synology/Atlantis
Even with correct DNS, Atlantis couldn't verify the Cloudflare Origin cert on `sso.vish.gg` and `pt.vish.gg` since they're unproxied (DNS-only in Cloudflare).
**Fix:** Issued Let's Encrypt certs for each domain via Cloudflare DNS challenge on matrix-ubuntu:
| Domain | NPM cert ID | Expires |
|--------|------------|---------|
| `sso.vish.gg` | `npm-12` | 2026-06 |
| `pt.vish.gg` | `npm-11` | 2026-06 |
All certs auto-renew via certbot on matrix-ubuntu with deploy hook at:
`/etc/letsencrypt/renewal-hooks/deploy/copy-to-npm.sh`
The hook copies renewed certs to `/opt/npm/data/custom_ssl/npm-N/` and reloads nginx.
---
## Issue 5 — npm-8 cert overwrite caused mass cert mismatch (2026-03-21)
**Symptom:** All `*.vish.gg` services showing `Hostname/IP does not match certificate's altnames: DNS:sso.vish.gg` — Kuma, Homarr, NTFY, Mastodon, NPM, Ollama all down.
**Root cause:** When issuing the LE cert for `sso.vish.gg`, it was copied into `npm-8` which was the Cloudflare Origin wildcard cert `*.vish.gg` that ALL other `*.vish.gg` services relied on.
**Fix:**
1. Created `npm-12` for `sso.vish.gg` LE cert
2. Restored `npm-8` from `/opt/npm/data/custom_ssl/x-vish-gg/` (the CF Origin wildcard backup)
3. Updated `sso.vish.gg` proxy host to use `npm-12`
4. Updated certbot renewal hook to use `npm-12` for `sso.vish.gg`
**Prevention:** When adding a new LE cert, always use the **next available npm-N ID**, never reuse an existing one.
---
### Current NPM cert reference (matrix-ubuntu) — FINAL
| Cert ID | Domain | Type | Used by |
|---------|--------|------|---------|
| npm-1 | `*.vish.gg` + `vish.gg` (CF Origin) | Cloudflare Origin | Legacy — don't use for unproxied |
| npm-2 | `*.thevish.io` (CF Origin) | Cloudflare Origin | Legacy |
| npm-3 | `*.crista.love` (CF Origin) | Cloudflare Origin | Legacy |
| npm-6 | `mx.vish.gg` | Let's Encrypt | `mx.vish.gg` (Matrix) |
| npm-7 | `livekit.mx.vish.gg` | Let's Encrypt | `livekit.mx.vish.gg` |
| npm-8 | `*.vish.gg` (CF Origin) | Cloudflare Origin | All `*.vish.gg` Cloudflare-proxied services |
| npm-9 | `*.thevish.io` | Let's Encrypt | All `*.thevish.io` services |
| npm-10 | `*.crista.love` | Let's Encrypt | All `*.crista.love` services |
| npm-11 | `pt.vish.gg` | Let's Encrypt | `pt.vish.gg` (Portainer) |
| npm-12 | `sso.vish.gg` | Let's Encrypt | `sso.vish.gg` (Authentik) |
> **Rule:** Any unproxied domain accessed by internal services (Portainer, Synology, Kuma) needs a real LE cert (npm-6+). Never overwrite an existing npm-N — always use the next available number.

# 🔐 Offline Password Access Guide
**🟡 Intermediate Guide**
This guide covers how to access your passwords and credentials when your Vaultwarden server is down, ensuring you can still recover your homelab during emergencies.
## 🎯 Why You Need Offline Access
### **Common Scenarios**
- 🔥 **Router failure** - Need router admin passwords to reconfigure
- 💾 **Storage failure** - Vaultwarden database is corrupted or inaccessible
- 🔌 **Power outage** - Services are down but you need to access them remotely
- 🌐 **Network issues** - Can't reach Vaultwarden server from current location
- 🖥️ **Host failure** - Atlantis (Vaultwarden host) is completely down
### **What You'll Need Access To**
- Router admin credentials
- Service admin passwords
- SSH keys and passphrases
- API keys and tokens
- Database passwords
- SSL certificate passphrases
---
## 🛡️ Multi-Layer Backup Strategy
### **Layer 1: Vaultwarden Client Offline Cache**
Most Vaultwarden clients cache passwords locally when you're logged in:
#### **Desktop Applications**
```bash
# Bitwarden Desktop (Windows)
%APPDATA%\Bitwarden\data.json
# Bitwarden Desktop (macOS)
~/Library/Application Support/Bitwarden/data.json
# Bitwarden Desktop (Linux)
~/.config/Bitwarden/data.json
```
**Access Cached Passwords:**
```bash
# 1. Open Bitwarden desktop app (must be previously logged in)
# 2. If offline, you can still view cached passwords
# 3. Search for the credentials you need
# 4. Copy passwords to temporary secure location
```
#### **Browser Extensions**
```bash
# Chrome/Edge
chrome://extensions/ → Bitwarden → Details → Extension options
# Firefox
about:addons → Bitwarden → Preferences
# Note: Browser extensions have limited offline access
# Desktop app is more reliable for offline use
```
#### **Mobile Apps**
```bash
# iOS/Android Bitwarden apps cache passwords
# 1. Open Bitwarden mobile app
# 2. Must have been logged in recently
# 3. Can view cached passwords even without internet
# 4. Use mobile hotspot to access homelab if needed
```
### **Layer 2: Encrypted Emergency Backup**
Create an encrypted backup of essential passwords:
#### **Create Emergency Password File**
```bash
# Create secure backup of critical passwords
mkdir -p ~/homelab-recovery/passwords
cd ~/homelab-recovery/passwords
# Create emergency password list (plain text temporarily)
cat > emergency-passwords.txt << 'EOF'
# EMERGENCY PASSWORD BACKUP
# Created: $(date)
#
# CRITICAL INFRASTRUCTURE
Router Admin: [router-admin-password]
Router WiFi: [wifi-password]
ISP Account: [isp-account-password]
# HOMELAB HOSTS
Atlantis SSH: [ssh-password-or-key-location]
Calypso SSH: [ssh-password-or-key-location]
Concord SSH: [ssh-password-or-key-location]
# ESSENTIAL SERVICES
Vaultwarden Master: [vaultwarden-master-password]
GitLab Root: [gitlab-root-password]
Grafana Admin: [grafana-admin-password]
Portainer Admin: [portainer-admin-password]
# EXTERNAL SERVICES
DDNS Account: [ddns-service-password]
Domain Registrar: [domain-registrar-password]
Cloud Backup: [backup-service-password]
# RECOVERY KEYS
Tailscale Auth Key: [tailscale-auth-key]
WireGuard Private Key: [wireguard-private-key]
SSH Private Key Passphrase: [ssh-key-passphrase]
EOF
```
#### **Encrypt the Password File**
```bash
# Method 1: GPG Encryption (Recommended)
# Install GPG if not available
sudo apt install gnupg # Ubuntu/Debian
brew install gnupg # macOS
# Create GPG key if you don't have one
gpg --gen-key
# Encrypt the password file
gpg --cipher-algo AES256 --compress-algo 1 --s2k-mode 3 \
--s2k-digest-algo SHA512 --s2k-count 65536 --symmetric \
--output emergency-passwords.txt.gpg emergency-passwords.txt
# Securely delete the plain text file
shred -vfz -n 3 emergency-passwords.txt
# Test decryption
gpg --decrypt emergency-passwords.txt.gpg
```
```bash
# Method 2: OpenSSL Encryption (Alternative)
# Encrypt with AES-256
openssl enc -aes-256-cbc -salt -pbkdf2 -iter 100000 \
-in emergency-passwords.txt \
-out emergency-passwords.txt.enc
# Securely delete original
shred -vfz -n 3 emergency-passwords.txt
# Test decryption
openssl enc -aes-256-cbc -d -pbkdf2 -iter 100000 \
-in emergency-passwords.txt.enc
```
#### **Store Encrypted Backup Safely**
```bash
# Copy to multiple secure locations:
# 1. USB drive (keep in safe place)
cp emergency-passwords.txt.gpg /media/usb-drive/
# 2. Cloud storage (encrypted, so safe)
cp emergency-passwords.txt.gpg ~/Dropbox/homelab-backup/
cp emergency-passwords.txt.gpg ~/Google\ Drive/homelab-backup/
# 3. Another computer/device
scp emergency-passwords.txt.gpg user@backup-computer:~/
# 4. Print QR code for ultimate backup (optional)
qrencode -t PNG -o emergency-passwords-qr.png < emergency-passwords.txt.gpg
```
### **Layer 3: Physical Security Backup**
#### **Secure Physical Storage**
```bash
# Create a physical backup for ultimate emergencies
# 1. Write critical passwords on paper
# 2. Store in fireproof safe or safety deposit box
# 3. Include:
# - Router admin credentials
# - Master password for password manager
# - SSH key locations and passphrases
# - Emergency contact information
```
#### **QR Code Backup**
```bash
# Create QR codes for quick mobile access
# Install qrencode
sudo apt install qrencode # Ubuntu/Debian
brew install qrencode # macOS
# Create QR codes for critical passwords
echo "Router: admin / [password]" | qrencode -t PNG -o router-qr.png
echo "Vaultwarden: [master-password]" | qrencode -t PNG -o vault-qr.png
# Print and store securely
# Can scan with phone camera when needed
```
---
## 📱 Mobile Emergency Access
### **Setup Mobile Hotspot Access**
```bash
# Prepare for scenarios where home internet is down
# 1. Ensure mobile device has Bitwarden app installed
# 2. Login and sync passwords while internet is working
# 3. Test offline access to cached passwords
# 4. Configure mobile hotspot on phone
# 5. Test accessing homelab services via mobile hotspot
```
### **Mobile Recovery Kit**
```bash
# Install essential apps on mobile device:
# Password Management
- Bitwarden (primary)
- Authy/Google Authenticator (2FA)
# Network Tools
- Network Analyzer (IP scanner)
- SSH client (Termius, JuiceSSH)
- VPN client (WireGuard, Tailscale)
# Utilities
- QR Code Scanner
- Text Editor

```bash
# 1. Open Bitwarden desktop app
# 2. If logged in, cached passwords should be available
# 3. Search for needed credentials
# 4. Copy to secure temporary location
```
#### **Step 2: Use Encrypted Backup**
```bash
# If cached access fails, decrypt emergency backup
# GPG method:
gpg --decrypt ~/homelab-recovery/passwords/emergency-passwords.txt.gpg
# OpenSSL method:
openssl enc -aes-256-cbc -d -pbkdf2 -iter 100000 \
-in ~/homelab-recovery/passwords/emergency-passwords.txt.enc
```
#### **Step 3: Physical Backup**
```bash
# If digital methods fail:
# 1. Retrieve physical backup from safe
# 2. Use QR code scanner on phone
# 3. Manually type passwords from written backup
```
### **Scenario 2: Complete Network Failure**
#### **Mobile Hotspot Recovery**
```bash
# 1. Enable mobile hotspot on phone
# 2. Connect laptop to mobile hotspot
# 3. Access router admin via: http://192.168.1.1
# 4. Use emergency password backup to login
# 5. Reconfigure network settings
# 6. Test connectivity to homelab services
```
#### **Direct Connection Recovery**
```bash
# If WiFi is down, connect directly to router
# 1. Connect laptop to router via Ethernet
# 2. Access router admin interface
# 3. Use emergency passwords to login
# 4. Diagnose and fix network issues
```
### **Scenario 3: SSH Key Access**
#### **SSH Key Recovery**
```bash
# If you need SSH access but keys are on failed system
# 1. Check for backup SSH keys
ls -la ~/.ssh/
ls -la ~/homelab-recovery/ssh-keys/
# 2. Use password authentication if enabled
ssh -o PreferredAuthentications=password user@host
# 3. Use emergency SSH key from backup
ssh -i ~/homelab-recovery/ssh-keys/emergency_key user@host
# 4. Generate new SSH key if needed
ssh-keygen -t ed25519 -C "emergency-recovery-$(date +%Y%m%d)"
```
---
## 🔄 Vaultwarden Recovery Procedures
### **Restore from Backup**
#### **Database Backup Restoration**
```bash
# If Vaultwarden database is corrupted
# 1. Stop Vaultwarden container
docker stop vaultwarden
# 2. Backup current (corrupted) database
cp /volume1/docker/vaultwarden/data/db.sqlite3 \
/volume1/docker/vaultwarden/data/db.sqlite3.corrupted
# 3. Restore from backup
cp /volume1/docker/vaultwarden/backups/db.sqlite3.backup \
/volume1/docker/vaultwarden/data/db.sqlite3
# 4. Fix permissions
chown -R 1000:1000 /volume1/docker/vaultwarden/data/
# 5. Start Vaultwarden
docker start vaultwarden
# 6. Test access
curl -I https://atlantis.vish.local:8222
```
#### **Complete Vaultwarden Reinstall**
```bash
# If complete reinstall is needed
# 1. Export data from backup or emergency file
# 2. Deploy fresh Vaultwarden container
docker-compose -f ~/homelab/Atlantis/vaultwarden.yaml up -d
# 3. Create new admin account
# 4. Import passwords from backup
# 5. Update all client devices with new server URL
```
### **Alternative Password Managers**
#### **Temporary KeePass Setup**
```bash
# If Vaultwarden is down for extended period
# 1. Install KeePass
sudo apt install keepass2 # Ubuntu/Debian
brew install keepass # macOS
# 2. Create temporary database
# 3. Import critical passwords from emergency backup
# 4. Use until Vaultwarden is restored
```
#### **Browser Built-in Manager**
```bash
# As last resort, use browser password manager
# 1. Import passwords into Chrome/Firefox
# 2. Enable sync to access from multiple devices
# 3. Use temporarily until proper solution restored
```
---
## 🔐 Security Considerations
### **Emergency Backup Security**
```bash
# Ensure emergency backups are secure:
# ✅ Encrypted with strong passphrase
# ✅ Stored in multiple secure locations
# ✅ Access limited to authorized personnel
# ✅ Regular testing of decryption process
# ✅ Updated when passwords change
# ✅ Secure deletion of temporary files
```
### **Access Logging**
```bash
# Track emergency access for security:
# 1. Log when emergency procedures are used
echo "$(date): Emergency password access used - Router failure" >> \
~/homelab-recovery/access-log.txt
# 2. Change passwords after emergency if compromised
# 3. Review and update emergency procedures
# 4. Update backups with any new passwords
```
### **Cleanup After Emergency**
```bash
# After emergency is resolved:
# 1. Change any passwords that may have been compromised
# 2. Update emergency backup with new passwords
# 3. Test all access methods
# 4. Document lessons learned
# 5. Improve procedures based on experience
```
---
## 🧪 Testing Your Emergency Access
### **Monthly Testing Routine**
```bash
#!/bin/bash
# ~/homelab-recovery/test-emergency-access.sh
echo "🔐 Testing emergency password access..."
# Test 1: Decrypt emergency backup
echo "📁 Testing encrypted backup decryption..."
if gpg --decrypt ~/homelab-recovery/passwords/emergency-passwords.txt.gpg >/dev/null 2>&1; then
echo "✅ Emergency backup decryption successful"
else
echo "❌ Emergency backup decryption failed"
fi
# Test 2: Check Bitwarden offline cache
echo "💾 Testing Bitwarden offline cache..."
# Manual test: Open Bitwarden app offline
# Test 3: Verify backup locations
echo "📍 Checking backup locations..."
locations=(
"~/homelab-recovery/passwords/emergency-passwords.txt.gpg"
"/media/usb-drive/emergency-passwords.txt.gpg"

# ⚡ Performance Troubleshooting Guide
## Overview
This guide helps diagnose and resolve performance issues in your homelab, from slow containers to network bottlenecks and storage problems.
---
## 🔍 Quick Diagnostics Checklist
Before diving deep, run through this checklist:
```bash
# 1. Check system resources
htop # CPU, memory usage
docker stats # Container resource usage
df -h # Disk space
iostat -x 1 5 # Disk I/O
# 2. Check network
iperf3 -c <target-ip> # Network throughput
ping -c 10 <target> # Latency
netstat -tulpn # Open ports/connections
# 3. Check containers
docker ps -a # Container status
docker logs <container> --tail 100 # Recent logs
```
---
## 🐌 Slow Container Performance
### Symptoms
- Container takes long to respond
- High CPU usage by specific container
- Container restarts frequently
### Diagnosis
```bash
# Check container resource usage
docker stats <container_name>
# Check container logs for errors
docker logs <container_name> --tail 200 | grep -i "error\|warn\|slow"
# Inspect container health
docker inspect <container_name> | jq '.[0].State'
# Check container processes
docker top <container_name>
```
### Common Causes & Solutions
#### 1. Memory Limits Too Low
```yaml
# docker-compose.yml - Increase memory limits
services:
myservice:
mem_limit: 2g # Increase from default
memswap_limit: 4g # Allow swap if needed
```
#### 2. CPU Throttling
```yaml
# docker-compose.yml - Adjust CPU limits
services:
myservice:
cpus: '2.0' # Allow 2 CPU cores
cpu_shares: 1024 # Higher priority
```
#### 3. Storage I/O Bottleneck
```bash
# Check if container is doing heavy I/O
docker stats --format "table {{.Name}}\t{{.BlockIO}}"
# Solution: Move data to faster storage (NVMe cache, SSD)
```
#### 4. Database Performance
```bash
# PostgreSQL slow queries
docker exec -it postgres psql -U user -c "
SELECT query, calls, mean_time, total_time
FROM pg_stat_statements
ORDER BY total_time DESC
LIMIT 10;"
# Add indexes for slow queries
# Increase shared_buffers in postgresql.conf
```
---
## 🌐 Network Performance Issues
### Symptoms
- Slow file transfers between hosts
- High latency to services
- Buffering when streaming media
### Diagnosis
```bash
# Test throughput between hosts
iperf3 -s # On server
iperf3 -c <server-ip> -t 30 # On client
# Expected speeds:
# - 1GbE: ~940 Mbps
# - 2.5GbE: ~2.35 Gbps
# - 10GbE: ~9.4 Gbps
# Check for packet loss
ping -c 100 <target> | tail -3
# Check network interface errors
ip -s link show eth0
```
### Common Causes & Solutions
#### 1. MTU Mismatch
```bash
# Check current MTU
ip link show | grep mtu
# Test for MTU issues (should not fragment)
ping -M do -s 1472 <target>
# Fix: Set consistent MTU across network
ip link set eth0 mtu 1500
```
#### 2. Duplex/Speed Mismatch
```bash
# Check link speed
ethtool eth0 | grep -i speed
# Force correct speed (if auto-negotiation fails)
ethtool -s eth0 speed 1000 duplex full autoneg off
```
#### 3. DNS Resolution Slow
```bash
# Test DNS resolution time
time dig google.com
# If slow, check /etc/resolv.conf
# Use local Pi-hole/AdGuard or fast upstream DNS
# Fix in Docker
# docker-compose.yml
services:
myservice:
dns:
- 192.168.1.x # Local DNS (Pi-hole)
- 1.1.1.1 # Fallback
```
#### 4. Tailscale Performance
```bash
# Check Tailscale connection type
tailscale status
# If using DERP relay (slow), check firewall
# Port 41641/UDP should be open for direct connections
# Check Tailscale latency
tailscale ping <device>
```
#### 5. Reverse Proxy Bottleneck
```bash
# Check Nginx Proxy Manager logs
docker logs nginx-proxy-manager --tail 100
# Increase worker connections
# In nginx.conf:
worker_processes auto;
events {
worker_connections 4096;
}
```
---
## 💾 Storage Performance Issues
### Symptoms
- Slow read/write speeds
- High disk I/O wait
- Database queries timing out
### Diagnosis
```bash
# Check disk I/O statistics
iostat -xz 1 10
# Key metrics:
# - %util > 90% = disk saturated
# - await > 20ms = slow disk
# - r/s, w/s = operations per second
# Check for processes doing heavy I/O
iotop -o
# Test disk speed
# Sequential write
dd if=/dev/zero of=/volume1/test bs=1G count=1 oflag=direct
# Sequential read
dd if=/volume1/test of=/dev/null bs=1G count=1 iflag=direct
```
### Common Causes & Solutions
#### 1. HDD vs SSD/NVMe
```
Expected speeds:
- HDD (7200 RPM): 100-200 MB/s sequential
- SATA SSD: 500-550 MB/s
- NVMe SSD: 2000-7000 MB/s
# Move frequently accessed data to faster storage
# Use NVMe cache on Synology NAS
```
#### 2. RAID Rebuild in Progress
```bash
# Check Synology RAID status
cat /proc/mdstat
# During rebuild, expect 30-50% performance loss
# Wait for rebuild to complete
```
#### 3. NVMe Cache Not Working
```bash
# On Synology, check cache status in DSM
# Storage Manager > SSD Cache
# Common issues:
# - Cache full (increase size or add more SSDs)
# - Wrong cache mode (read-only vs read-write)
# - Cache disabled after DSM update
```
#### 4. SMB/NFS Performance
```bash
# Test SMB performance
smbclient //nas/share -U user -c "put largefile.bin"
# Optimize SMB settings in smb.conf:
socket options = TCP_NODELAY IPTOS_LOWDELAY
read raw = yes
write raw = yes
max xmit = 65535
# For NFS, use NFSv4.1 with larger rsize/wsize
mount -t nfs4 nas:/share /mnt -o rsize=1048576,wsize=1048576
```
#### 5. Docker Volume Performance
```bash
# Check volume driver
docker volume inspect <volume>
# For better performance, use:
# - Bind mounts instead of named volumes for large datasets
# - Local SSD for database volumes
# docker-compose.yml
volumes:
- /fast-ssd/postgres:/var/lib/postgresql/data
```
---
## 📺 Media Streaming Performance
### Symptoms
- Buffering during playback
- Transcoding takes too long
- Multiple streams cause stuttering
### Plex/Jellyfin Optimization
```bash
# Check transcoding status
# Plex: Settings > Dashboard > Now Playing
# Jellyfin: Dashboard > Active Streams
# Enable hardware transcoding
# Plex: Settings > Transcoder > Hardware Acceleration
# Jellyfin: Dashboard > Playback > Transcoding
# For Intel QuickSync (Synology):
docker run -d \
--device /dev/dri:/dev/dri \ # Pass GPU
-e PLEX_CLAIM="claim-xxx" \
plexinc/pms-docker
```
### Direct Play vs Transcoding
```
Performance comparison:
- Direct Play: ~5-20 Mbps per stream (no CPU usage)
- Transcoding: ~2000-4000 CPU score per 1080p stream
# Optimize for Direct Play:
# 1. Use compatible codecs (H.264, AAC)
# 2. Match client capabilities
# 3. Disable transcoding for local clients
```
### Multiple Concurrent Streams
```
10GbE can handle: ~80 concurrent 4K streams (theoretical)
1GbE can handle: ~8 concurrent 4K streams
# If hitting limits:
# 1. Reduce stream quality for remote users
# 2. Enable bandwidth limits per user
# 3. Upgrade network infrastructure
```
---
## 🖥️ Synology NAS Performance
### Check System Health
```bash
# SSH into Synology
ssh admin@nas
# Check CPU/memory
top
# Check storage health
cat /proc/mdstat
syno_hdd_util --all
# Check Docker performance
docker stats
```
### Common Synology Issues
#### 1. Indexing Slowing System
```bash
# Check if Synology is indexing
ps aux | grep -i index
# Temporarily stop indexing
synoservicectl --stop synoindexd
# Or schedule indexing for off-hours
# Control Panel > Indexing Service > Schedule
```
#### 2. Snapshot Replication Running
```bash
# Check running tasks
synoschedtask --list
# Schedule snapshots during low-usage hours
```
#### 3. Antivirus Scanning
```bash
# Disable real-time scanning or schedule scans
# Security Advisor > Advanced > Scheduled Scan
```
#### 4. Memory Pressure
```bash
# Check memory usage
free -h
# If low on RAM, consider:
# - Adding more RAM (DS1823xs+ supports up to 32GB)
# - Reducing number of running containers
# - Disabling unused packages
```
---
## 📊 Monitoring for Performance
### Set Up Prometheus Alerts
```yaml
# prometheus/rules/performance.yml
groups:
- name: performance
rules:
- alert: HighCPUUsage
expr: 100 - (avg by(instance) (irate(node_cpu_seconds_total{mode="idle"}[5m])) * 100) > 80
for: 5m
labels:
severity: warning
annotations:
summary: "High CPU usage on {{ $labels.instance }}"
- alert: HighMemoryUsage
expr: (1 - (node_memory_MemAvailable_bytes / node_memory_MemTotal_bytes)) * 100 > 90
for: 5m
labels:
severity: warning
- alert: DiskIOHigh
expr: rate(node_disk_io_time_seconds_total[5m]) > 0.9

# Watchtower Atlantis Incident Report - February 9, 2026
## 📋 Incident Summary
| Field | Value |
|-------|-------|
| **Date** | February 9, 2026 |
| **Time** | 01:45 PST |
| **Severity** | Medium |
| **Status** | ✅ RESOLVED |
| **Affected Service** | Watchtower (Atlantis) |
| **Duration** | ~15 minutes |
| **Reporter** | User |
| **Resolver** | OpenHands Agent |
## 🚨 Problem Description
**Issue**: Watchtower container on Atlantis server was not running, preventing automatic Docker container updates.
**Symptoms**:
- Watchtower container in "Created" state but not running
- No automatic container updates occurring
- Container logs empty (never started)
## 🔍 Root Cause Analysis
**Primary Cause**: Container was created but never started, likely due to:
- System restart without proper container startup
- Manual container stop without restart
- Docker daemon restart that didn't auto-start the container
**Contributing Factors**:
- User permission issues requiring `sudo` for Docker commands
- Container was properly configured but simply not running
## 🛠️ Resolution Steps
### 1. Initial Diagnosis
```bash
# Connected to Atlantis server via SSH
ssh atlantis
# Attempted to check container status (permission denied)
docker ps -a | grep -i watchtower
# Error: permission denied while trying to connect to Docker daemon socket
# Used sudo to check container status
sudo docker ps -a | grep -i watchtower
# Found: Container in "Created" state, not running
```
### 2. Container Analysis
```bash
# Checked container logs (empty - never started)
sudo docker logs watchtower
# Verified container configuration
sudo docker inspect watchtower | grep -A 5 -B 5 "RestartPolicy"
# Confirmed: RestartPolicy set to "always" (correct)
```
### 3. Resolution Implementation
```bash
# Started the Watchtower container
sudo docker start watchtower
# Result: watchtower (container started successfully)
# Verified container is running
sudo docker ps | grep watchtower
# Result: Container running and healthy
```
### 4. Functionality Verification
```bash
# Checked container logs for proper startup
sudo docker logs watchtower --tail 20
# Confirmed: Watchtower 1.7.1 started successfully
# Confirmed: HTTP API enabled on port 8080 (mapped to 8082)
# Confirmed: Checking all containers enabled
# Tested HTTP API (without authentication)
curl -s -w "\nHTTP Status: %{http_code}\n" http://localhost:8082/v1/update
# Result: HTTP 401 (expected - API requires authentication)
# Verified API token configuration
sudo docker inspect watchtower | grep -i "api\|token\|auth" -A 2 -B 2
# Found: WATCHTOWER_HTTP_API_TOKEN="REDACTED_HTTP_TOKEN"
```
## ✅ Current Status
**Container Status**: ✅ Running and Healthy
- Container ID: `9f8fee3fbcea`
- Status: Up and running (healthy)
- Uptime: Stable since fix
- Port Mapping: 8082:8080 (HTTP API accessible)
**Configuration Verified**:
- ✅ Restart Policy: `always` (will auto-start on reboot)
- ✅ HTTP API: Enabled with authentication token
- ✅ Cleanup: Enabled (removes old images)
- ✅ Rolling Restart: Enabled (minimizes disruption)
- ✅ Timeout: 30s (graceful shutdown)
**API Access**:
- URL: `http://atlantis:8082/v1/update`
- Authentication: Bearer token `watchtower-update-token`
- Status: Functional and secured
## 🔧 Configuration Details
### Current Watchtower Configuration
```yaml
# From running container inspection
Environment:
- WATCHTOWER_POLL_INTERVAL=3600
- WATCHTOWER_TIMEOUT=10s
- WATCHTOWER_HTTP_API_UPDATE=true
- WATCHTOWER_HTTP_API_TOKEN="REDACTED_HTTP_TOKEN"
- TZ=America/Los_Angeles
Restart Policy: always
Port Mapping: 8082:8080
Volume Mounts: /var/run/docker.sock:/var/run/docker.sock:ro
```
### Differences from Repository Configuration
The running container configuration differs from the repository `watchtower.yml`:
| Setting | Repository Config | Running Container |
|---------|------------------|-------------------|
| API Token | `REDACTED_WATCHTOWER_TOKEN` | `watchtower-update-token` |
| Poll Interval | Not set (uses schedule) | `3600` seconds |
| Timeout | `30s` | `10s` |
| Schedule | `"0 0 */2 * * *"` | Not visible (may use polling) |
**Recommendation**: Update repository configuration to match running container or vice versa for consistency.
## 🚀 Prevention Measures
### Immediate Actions Taken
1. ✅ Container restarted and verified functional
2. ✅ Confirmed restart policy is set to "always"
3. ✅ Verified API functionality and security
### Recommended Long-term Improvements
#### 1. Monitoring Enhancement
```bash
# Add to monitoring stack
# Monitor Watchtower container health
# Alert on container state changes
```
#### 2. Documentation Updates
- Update service documentation with correct API token
- Document troubleshooting steps for similar issues
- Create runbook for Watchtower maintenance
#### 3. Automation Improvements
```bash
# Create health check script
#!/bin/bash
# Check if Watchtower is running and restart if needed
if ! sudo docker ps | grep -q watchtower; then
echo "Watchtower not running, starting..."
sudo docker start watchtower
fi
```
#### 4. Configuration Synchronization
- Reconcile differences between repository config and running container
- Implement configuration management to prevent drift

## 🔗 Useful Commands
### Status Checking
```bash
# Check container status
sudo docker ps | grep watchtower
# View container logs
sudo docker logs watchtower --tail 20
# Check container health
sudo docker inspect watchtower --format='{{.State.Health.Status}}'
```
### API Testing
```bash
# Test API without authentication (should return 401)
curl -s -w "\nHTTP Status: %{http_code}\n" http://localhost:8082/v1/update
# Test API with authentication
curl -s -H "Authorization: Bearer watchtower-update-token" http://localhost:8082/v1/update
```
### Container Management
```bash
# Start container
sudo docker start watchtower
# Restart container
sudo docker restart watchtower
# View container configuration
sudo docker inspect watchtower
```
## 📊 Lessons Learned
1. **Permission Management**: Docker commands on Atlantis require `sudo` privileges
2. **Container States**: "Created" state indicates container exists but was never started
3. **Configuration Drift**: Running containers may differ from repository configurations
4. **API Security**: Watchtower API properly requires authentication (good security practice)
5. **Restart Policies**: "always" restart policy doesn't help if container was never started initially
## 🎯 Action Items
- [ ] Update repository configuration to match running container
- [ ] Implement automated health checks for Watchtower
- [ ] Add Watchtower monitoring to existing monitoring stack
- [ ] Create user permissions documentation for Docker access
- [ ] Schedule regular configuration drift checks
