I'm not sure why the user authentication is failing for you with go-l2tp's kl2tpd, you could try disabling all of the authentication methods in the PPP settings other than MSCHAPv2.
You could also try switching to xl2tpd and see if you have the same problem, e.g.: sudo apt install xl2tpd sudo apt purge go-l2tp the other Linux distros you mentioned don't ship with go-l2tp, so they would have been defaulting to xl2tpd. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/2068687 Title: L2TP VPN is not working in Ubuntu 24.04 To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/network-manager-l2tp/+bug/2068687/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
