AOVPN can’t find user cert error 798
I have an RRAS server with separate NPS server onprem trying to configure AOVPN. I’m using public certs for NPS and RRAS and also Entra short-lived certs, root cert is installed on the domain and available to the clients. Entra replaces onprem CA and allows use of conditional access policy.
When the client attempts to connect, it connects to entra and generates a one hour cert in the user cert store. However, the connection fails and not sure where the issue is. I already checked and user cert is valid, has private key and trusts the root, has client authentication. Not much info in NPS logs, it doesn’t appear the client is actually trying to connect. How would I troubleshoot this ?
Error message on the client:
A certificate could not be found that can be used with this Extensible Authentication Protocol. (Error 798)
