Hi, we have the following problem,

We are using Always on Azure VPN client with Azure Virtual WAN and AD authentication.

The following problem: the VPN connection is interrupted at irregular intervals and then reconnects automatically.
We get an disconnect, with "[Error] Exception: "
My first assumption would be that the internet connection is interrupted, but I have already managed to rule that out.

I tried it with Azure VPN Client Version: 3.1.3.0 and 3.2.0.0

Our VPN Client Log looks like this:

    We had "random" disconnects. We had pushed our VPN profile out with Intune. We were using the Intune-pushed VPN profile and found that the Intune syncs were causing the disconnects. I asked my users to export the profile, save it, and reimport it, and then use the VPN connection from the manually imported profile. That one works and does not get dropped when an Intune sync occurs. Hope this helps.
