### Email Testing
```bash
# Test account creation (sends verification email)
curl -X POST http://localhost:14702/auth/account/create \
  -H "Content-Type: application/json" \
  -d '{"email": "test@example.com", "password": "TestPass123!"}'

- **Helgrier**: user@example.com (password: "REDACTED_PASSWORD"

## 🚨 Troubleshooting

### Common Issues
1. **Service won't start**: Check port availability, restart with manage-services.sh
2. **Email not received**: Check spam folder, verify SMTP credentials in Revolt.overrides.toml
3. **SSL issues**: Verify certificate renewal with `certbot certificates`
4. **Frontend not loading**: Check nginx configuration and service status

### Log Locations
- **Services**: *.log files in /root/stoatchat/
- **Nginx**: /var/log/nginx/error.log
- **System**: /var/log/syslog

### Health Checks
```bash
# Quick service check
for port in 14702 14703 14704 14705 14706; do
  echo "Port $port: $(curl -s -o /dev/null -w "%{http_code}" http://localhost:$port/)"
done

# API health
curl -s http://localhost:14702/ | jq '.revolt'
```

## 💾 Backup Strategy

### Automated Backups
- **Schedule**: Daily at 2 AM via cron
- **Location**: /root/stoatchat-backups/
- **Retention**: Manual cleanup (consider implementing rotation)

### Backup Contents
- Configuration files (Revolt.toml, Revolt.overrides.toml)
- SSL certificates
- Nginx configuration
- User uploads and file storage

### Recovery Process
1. Stop services: `./manage-services.sh stop`
2. Restore: `./restore.sh /path/to/backup`
3. Start services: `./manage-services.sh start`

## 🔄 Deployment Process

### For New Machines
1. Follow DEPLOYMENT_DOCUMENTATION.md
2. Update domain names in configurations
3. Configure SMTP credentials
4. Obtain SSL certificates
5. Test all services

### Updates
1. Backup current system: `./backup.sh`
2. Stop services: `./manage-services.sh stop`
3. Pull updates: `git pull origin main`
4. Rebuild: `cargo build --release`
5. Start services: `./manage-services.sh start`

## 📊 Monitoring

### Performance Metrics
- **CPU/Memory**: Monitor with `top -p $(pgrep -d',' revolt)`
- **Disk Usage**: Check with `df -h` and `du -sh /root/stoatchat`
- **Network**: Monitor connections with `netstat -an | grep -E "(14702|14703|14704|14705|14706)"`

### Maintenance Schedule
- **Daily**: Check service status, review error logs
- **Weekly**: Run backups, check SSL certificates
