# Common Xano Connection Issues

If you are seeing connection issues, red errors in the Swagger validation, or missing endpoints, here are some things to check:

* **Default API group** is still connected to Adalo
* Required endpoints like `Login`, `Sign Up`, and `Me` are still in place (especially if using Xano for user authentication)
* Your Swagger documentation is valid (green checkmark in Xano settings)
* No required endpoints have been deleted or moved between API groups

If you change anything in Xano, you may need to **reconnect the API base** or **manually reset** your data connections in Adalo.
