## 🛠️ Troubleshooting
### Common Issues
#### 1. Port Already in Use
**Symptom**: Deployment shows port occupation warning
```
⚠️ The following ports are already in use: 3000, 3001
```
**Solution**:
```bash
# Method 1: Modify port configuration
echo "FRONTEND_PORT=8080" >> .env
echo "BACKEND_PORT=8081" >> .env
# Method 2: Stop programs using the ports
sudo ss -tulpn | grep :3000
sudo kill -9 <PID>
```
#### 2. Insufficient Memory
**Symptom**: Containers fail to start or restart frequently
**Solution**:
```bash
# Check memory usage
free -h
# Add swap space (temporary solution)
sudo fallocate -l 1G /swapfile
sudo chmod 600 /swapfile
sudo mkswap /swapfile
sudo swapon /swapfile
```
#### 3. Docker Permission Issues
**Symptom**: Permission denied errors
**Solution**:
```bash
# Add user to docker group
sudo usermod -aG docker $USER
# Re-login or refresh group permissions
newgrp docker
```
#### 4. Service Inaccessible
**Symptom**: Browser cannot open pages
**Solution**:
```bash
# 1. Check service status
docker-compose ps
# 2. Check health status
curl http://localhost:3001/health
curl http://localhost:3000/api/health
# 3. View detailed logs
docker-compose logs -f
# 4. Check firewall
sudo ufw status
```
#### 5. WebRTC Connection Failure
**Symptom**: Cannot establish P2P connections
**Solution**:
```bash
# Enable TURN server
bash deploy.sh --with-turn
