Missing steps to enable Multi-Factor Auth Client and Multi-Factor Auth Connector

[Absoblogginlutely]

We went through all these steps and kept getting the following errors showing up.
NPS Extension for Azure MFA: CID: 341b704d-03f1-4ba6-ae92-eb19ae2f2bf3 :Exception in Authentication Ext for User myusername :: ErrorCode:: CID :341b704d-03f1-4ba6-ae92-eb19ae2f2bf3 ESTS_TOKEN_ERROR Msg:: Verify the client certificate is properly enrolled in Azure against your tenant and the server can access URL in Registry STS_URL.

Went through all the troubleshooting steps above, no joy.
Ran the following to enable the relevant apps -
Set-MsolServicePrincipal -AppPrincipalId "981f26a1-7f43-403b-a875-f8b09b8cd720" -AccountEnabled $True
Set-MsolServicePrincipal -AppPrincipalId "1f5530b3-261a-47a9-b357-ded261e17918" -AccountEnabled $True

Restarted NPS server - now able to get Push notifications when vpn'ing in.
Hope this helps someone else configure this (there are a lot of search results for this error but not many fixes documented).

Why is this still an issue? I just installed the Azure MFA NPS extension and ran into the same issue.
