Hey, it seems Google Authenticator for MFA has stoped working, QR images for enrrollement are not properly being generated.
It seems google has finally deprecated it and all querys to https://chart.googleapis.com/ are failing with a 404 error.

Post where it is recommended to switch to another API: https://support.google.com/docs/thread/251700701
