I am trying to configure a NPS server so I can leverage Azure MFA. Installed the latest extension version from MS. The NPS server was working for all VPN users before.
The event viewer shows this error when trying to connect "An NPS extension dynamic link library (DLL) that is installed on the NPS server rejected the connection request"
I reinstalled the NPS extension, restarted the server but I still get the same error. Also have run Azure MFA NPS Extension Health Check script from Github. Have all the logs in a zip file for review.
