What is event 20227 error code --1878457588
I am trying to find out why users keep disconnecting from MS AOVPN. They have user tunnel created on Intune configuration profile, that gets a 1 hour cert from the Azure VPN Conditonal Access 1 hour certifcates, which the client then uses to connect to VPN and NPS on premise server. In the users logs there is a regualr event IDs of20221 - started dialing vpn connection
20223 - username Successfully established link to remote access server
20224 - link to the remote access server has been established by user username
20225 - username has dialed a connection named UserTunnel to the Remote Access Server which has successfully connected
then get the following soon after
"CoId={F98A0C00-9C66-0002-2BA6-94F9669CDA01}: The link to the Remote Access Server has been established by user ACADEMIC*username*.
20291 - UserTunnel requires attention.
20227 - CoId={F98A0C00-9C66-0002-2BA6-94F9669CDA01}: The user ACADEMIC*username* dialed a connection named UserTunnel which has failed. The error code returned on failure is -1878457588." Get mostly these events
Or
