• Check firewall settings
• Confirm correct port mapping

Performance issues

• Monitor resource usage: docker stats
• Check available disk space: df -h
• Review service logs for errors

# Check service status
docker-compose ps

# View real-time logs
docker-compose logs -f cocalc

# Restart service
docker-compose restart cocalc

# Update service
