Error Message "No issuer configured for OpenID Connect provider" when attempting to login

[BrianLester]

One of our teachers got "No issuer configured for OpenID Connect provider"

Instructure responded that this was an open issue

I was able to create a secondary login for the teacher , but I just encountered the same error when I tried to log in to our Beta instance.

Any ideas, workarounds, or experience with this problem would be helpful. Thanks!
