I wish I would have come across this post earlier! So we have all of this setup, but an issue we are running into is that the authentication session gets closed prior to some people completing their authentication factor. We're seeing this most often with Phone call / Push notification methods where people take upwards of 30-40 seconds to complete.
Steve, we have the same issue on our end. Workspaceone access with NPS Azure MFA agent. We only get around 15 seconds to approve on the phone.. Do you know the solution to fix this issue?
Currently the radius adapter setting is @ 60 seconds.. Still no resolution..
