I've spent half an hour debugging same problem and I vote for 60seconds timeout as my server logs show following:
TLS Error: TLS key negotiation failed to occur within 60 seconds (check your network connectivity) where 60 equals handshake_window from openvpn-2.0.7 soruces. 60 seconds is default openvpn setting and I assume that network-manager-openvpn should use it. -- timing problem https://bugs.launchpad.net/bugs/117992 You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
