While creating a new user or signing up someone. I’m getting this error:
```plaintext
## Error 400: redirect_uri_mismatch
You can't sign in to this app because it doesn't comply with Google's OAuth 2.0 policy.
If you're the app developer, register the redirect URI in the Google Cloud Console.
```
What can that be due to?

What did you configure as the redirect URI on Google side ?

Just go to `yourforum.example.com/users/admin-login` to log in and configure it.
