OS version: BYZANTIUM
Upstream bug report: https://gitlab.gnome.org/GNOME/NetworkManager-openvpn/-/issues/64
Fix merged: https://gitlab.gnome.org/GNOME/NetworkManager-openvpn/-/merge_requests/34
I request fix to be backported, as the bug prevents connecting to Librem Tunnel (and some other OpenVPN services) to connect.
