2. Find the following error in the logs:

```
OAuthTokenEndpointException - OAuth token endpoint error: {"error":"invalid_client","error_description":"AADSTS7000215: Invalid client secret provided.
```

3. Confirm that the secret sent in the request is the client secret value, not the client secret ID, for a secret added to the application.
4. Go to the Devolutions Server web app in the Entra ID Portal.
   1. Make sure the [API permission is properly set and granted](https://docs.devolutions.net/server/kb/how-to-articles/azure-portal-configuration-guide-microsoft-authentication/#in-the-azure-portal-3) in Entra ID's ***Home*** – ***App registration*** – ***API permissions***. Also ensure that the application registration is configured to ***Web*** and check if the address is correct.
   2. Create a new secret and copy its value. Set a reminder one month before its expiration using your preferred method.
5. In the Devolutions Server web interface, head over to ***Administration*** – ***Server settings*** – ***Authentication*** – ***Microsoft authentication***. Then:
   1. Paste the new client secret.
   2. Disable ***Use specific client ID for users and user groups cache***..
   3. Click on the ***Reset cache*** button.
   4. Save your changes.
