 ## Troubleshooting
 
 *   **Check Backend Logs:** `docker logs flic-webhook-webpush`. Look for errors related to configuration, file access, JSON parsing, authentication, or sending push notifications.
+    * The server logs all headers received from Flic requests to help with debugging. Look for lines starting with `DEBUG - All headers received:` to see all headers sent by the Flic button.
 *   **Check Traefik Logs:** `docker logs traefik`. Look for routing errors or certificate issues.
 *   **Verify `.env`:** Ensure all required variables are set correctly, especially VAPID keys and Traefik settings.
 *   **Verify `labels`:** Double-check that variables were correctly substituted manually and match your `.env` and Traefik setup.
