Today, after an apt full-upgrade package upgrade, my interfaces stopped working.
I am using WGDashboard + AmneziaWG Linux Kernel Module on Debian 12.

I am experiencing something similar. I cannot establish a connection. The same configuration works fine on Windows, but I cannot connect on Debian 12.

I made some strange discovery. If I remove S1, S2, H1-H4 from client config - it connects fine. How it is even possible...
