+## Troubleshooting
+
+### Debug mode
+
+> This should never be used in a production environment.
+
+For security reasons, authentication issues will always return an `HTTP 401` error code without any detail.
+
+It is possible to enable the debug mode in `config.json.php` 
+to get the actual error message in the HTTP response body with:
+
+```json
+{
+  "dev": {
+    "debug": true
+  }
+}
+```
