MFA and/or device registration

[whaleva]

Azure AD Provider has worked well for us for over a year now. We have stumbled lately when trying to enforce conditional access off network using MFA and/or device registration.

In DNN we receive the generic “A critical error has occurred.” on client side, and event log we see a Page Load Exception with the following details:
InnerMessage:
There was an error processing the credentials. Contact your system administrator.
InnerStackTrace:

These are the versions we are currently running:

1. Evoq Content 8.5
2. DNN Azure Active Directory Authorization Provider Version 01.00.05

We have been successfully using the MFA features on Azure AD with this provider for a long time now. Closing this issue as old one.
