I recently upgraded to fedora 25. Since then my VPN connection via openconnect (Cisco AnyConnect Compatible VPN) ceased to work.
When I now try to define a new equivalent VPN connection, I get the message
Error: unable to load VPN connection editor
This appears under both, Wayland and X. I have OpenConnect version v7.07; and I have NetworkManager-openconnect-1.2.4-1.fc25.x86_64.
Can you think of ways of getting the editor to work again? Or Can you point to a way to manually define such a connection, circumventing gnome?
