Clients disconnected after x amount of time with NPS+AzureMFA

[jmunoz]

I have to different installations. One using NPS as a radius server and another using my Identity Providers's RADIUS server. When I used Okta for RADIUS everything works fine. When I use local logins (without radius) everything is fine. When I use our on-remises NPS server for authentication, users are able to authenticate, they get the AzureMFA request, however after a few hours they get kicked off. OpenVPN AS support checked all the log and everything looks fine on the server side and suggested it was something with the RADIUS server. I don't have any timeout's setup as condition. Not sure of the AzureMFA might be doing something. Any one experience something similar?
