Do you have a problem during or after connecting?

eduVPN won't connect. Two NetworkManager connections are created (eduVPN for Wireguard and <profile name>-ovpn... for openVPN). I have no idea why, it happens even on profiles with OpenVPN disabled.

"/etc/netplan" ... not really NetworkManager.
But: 100.67.224.166/0 or did you mean 100.67.224.166/24 resp. an appropriate subnet mask?

I suppose that's the bug. The profile is /27

Best,

Also I don't use Ubuntu. I know there should be netplan by default which uses systemd-networkd. I have no idea how NM and netplan interact if both are installed.

Yeah. I tried that several times. I deleted all eduVPN related connections and retried.

I have a similar issue but not exactly same. I use kubuntu 24.04 (LTS release).

eduVPN GUI version: 4.7.2
eduvpn-common version: 5.0.2

I tried to activate my eduvpn last week and it stopped working. Instead it got stuck in the opening mode and restarted my networkmanager. I don't have a reason in the networkmanager log as to why it restarts.

NetworkManager[218016]: **

this is definitely #609, which could be fixed by nmcli con delete eduVPN. Note that the only people that are having this specific issue are using ubuntu, so I don't think this is a client issue.

It is a laptop of a colleague of mine. I'm responsible for eduVPN at Masaryk University so I wrote the issue. Apologies, I should've clarified that.

The problematic systems is indeed Ubuntu and deleting stale connections via nmcli does not help.

Two NetworkManager connections are created (eduVPN for Wireguard and -ovpn... for openVPN). I have no idea why, it happens even on profiles with OpenVPN disabled.

I don't see how this is possible, the client never puts the profile in the openVPN connection name. Are you sure this is not from a manual config download? Did you try removing that profile?

It's been a while since I've used Ubuntu and I’m not familiar with "/etc/netplan" either, but if I understood it correctly it acts as a wrapper whose configuration takes precedence? If so, the configuration in must be repaired here:

It's not really possible for me to help with anything unless I can get some sort of test account, this seems to be too profile specific. I cannot reproduce any of these issues on a clean Ubuntu 26.04 VM
