# Full node troubleshooting

## Troubleshooting

### Port forwarding not working

**Issue**: Your node cannot connect to peers.

**Solutions**:

* Verify your external IP address matches the `P2P_IP` setting
* Check firewall rules on your router and local machine
* Test connectivity using: `nc -zv [your-ip] 40400`

### Node not syncing

**Issue**: Your node is not synchronizing with the network.

**Solutions**:

* Check L1 endpoint connectivity
* Verify both execution and consensus clients are fully synced
* Review logs for specific error messages
* Ensure L1 endpoints support high throughput

### Docker issues

**Issue**: Container won't start or crashes.

**Solutions**:

* Ensure Docker and Docker Compose are up to date
* Check disk space availability
* Verify the `.env` file is properly formatted
* Review container logs: `docker compose logs aztec-node`
