I had the same problem of losing connection after upgrading to Ubuntu 22.04. After reading on several pages all over the Internet for solutions, I found someone saying that Ubuntu 22.04 uses a new and more secure version of OpenSSL (if I remember correctly). This would force some people to use more secure "protocols". I was already using them on my router so it made no sense why it was still not working. Then I found someone explaining that for any change you make to the OpenVPN server you MUST also update the CERTIFICATES... which I had not done.
After updating the CERTIFICATES on the OpenVPN server (my router), my Ubuntu 22.04 client can now connect without any problems. I hope this helps some people that have the same problem as me. -- 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 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
