+## 🔧 Troubleshooting
+
+### WhatsApp Webhook Configuration
+
+If you're seeing "POST 405 Method Not Allowed" errors in your logs, this usually means:
+
+1. **Webhook URL Configuration**: Make sure your WhatsApp webhook URL is set to:
+   - **Correct**: `https://your-domain.com/webhook`
+   - **Incorrect**: `https://your-domain.com/` (root path)
+
+2. **Environment Variables**: Ensure your `CALLBACK_URL` in the `.env` file matches exactly what you configured in Facebook/WhatsApp Business:
+   ```env
+   CALLBACK_URL=https://your-domain.com/webhook
+   ```
+
+3. **Facebook Configuration**: In your Facebook App settings under WhatsApp > Configuration, set:
+   - **Webhook URL**: `https://your-domain.com/webhook`
+   - **Verify Token**: Must match your `VERIFY_TOKEN` environment variable
+
+### Common Issues
+
+- **Container fails to start**: Check that all required environment variables are set
+- **WhatsApp not responding**: Verify webhook URL and verify token match Facebook configuration
+- **Model loading errors**: Ensure the model file exists in `assets/models/`
+
+### Health Check Endpoints
+
+- `GET /health` - Basic health check
+- `GET /health/detailed` - Detailed component status
+
