I'm having the same issue here, been fighting with it all day. Interestingly though I have two identical builds (except specific device drivers) Both Win 11 22H2 and one connects and works fine the other doesn't.
With the failing machine I set a ping going to ping my DC. When I connected the SSL Vpn the ping replied for a few seconds then stopped. If I leave it connected it will on occasion reply. On a couple of occasions it would reply for a large period of time before failing again.
I've tried the following.
Disabled all IPv6 in all networking devices.
Uninstalled and installed the VPN only version
Tried a different wifi connection
Uninstalled all windows updates
Uninstalled my RSAT tools
KB2693643 isn't installed on my machine so couldn't try that.
So now i'm facing the prospect of having to re-image the machine which I really don't want to do.
Checked the logs and I see the "Did not find interface for local_gwy 0786d40a" entry as well.
I would appreciate it if anyone has any further experience with this issue.
