Authentication Error. Failed to fetch user/group information from the identity provider.

What is the issue you’re encountering

Verifying Cloudflare Warp account with Azure login

What steps have you taken to resolve the issue?

Tried a few times via the Cloudflare Warp authentication in the preferences Account section. It redirects to the web browser like it is supposed to, it recognizes our Warp instance, press next to login. Then the user puts in user name and password and it returns the error in the image attached to this ticket ‘Authentication Error. Failed to fetch user/group information from the identity provider’.

What are the steps to reproduce the issue?

Tried multiple times the same way. Waited a bit and tried again.
