FYI In the `/var/log/syslog` there was a message about inconsistent cipher between client and server ("Failed to negociate cipher with server.")
I fixed the problem by: - editing the file `/etc/NetworkManager/system-connections/(connectionname).nmconnection` - adding in the vpn section the line `cipher=BF-CBC` Thanks to https://askubuntu.com/questions/1407774/cant-connect-to-vpn- after-upgrading-to-ubuntu-22-04 that helped me finding the file and knowing the available options. -- You received this bug notification because you are a member of Desktop Packages, which is subscribed to network-manager-openvpn in Ubuntu. https://bugs.launchpad.net/bugs/1969274 Title: openvpn client no longer connects in 22.04 until certificate update Status in network-manager-openvpn package in Ubuntu: New Bug description: Client no longer connects. previous version had no problem ProblemType: Bug DistroRelease: Ubuntu 22.04 Package: network-manager-openvpn 1.8.18-1 ProcVersionSignature: Ubuntu 5.15.0-25.25-generic 5.15.30 Uname: Linux 5.15.0-25-generic x86_64 ApportVersion: 2.20.11-0ubuntu82 Architecture: amd64 CasperMD5CheckResult: pass CurrentDesktop: ubuntu:GNOME Date: Sat Apr 16 15:09:56 2022 InstallationDate: Installed on 2022-04-15 (0 days ago) InstallationMedia: Ubuntu 22.04 LTS "Jammy Jellyfish" - Beta amd64 (20220329.1) SourcePackage: network-manager-openvpn UpgradeStatus: No upgrade log present (probably fresh install) To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/network-manager-openvpn/+bug/1969274/+subscriptions -- Mailing list: https://launchpad.net/~desktop-packages Post to : desktop-packages@lists.launchpad.net Unsubscribe : https://launchpad.net/~desktop-packages More help : https://help.launchpad.net/ListHelp
