When I’m trying to activate it popup with login and password fields appear. And after providing credentials
nothing happening. Only in logs I can find following error

лип 08 04:33:49 DzirT-LT NetworkManager[655]: [1499477629.2324] vpn-connection[0x5591dfacc270,8e337ac8-43f6-4a18-bd50-65d004d42e3e,“VPN1”,0]: Failed to request VPN secrets #3: No agents were available for this request.

See the same behavior also on the virtual machine installed from the same latest Netrunner image.

Seems like the vpn connection type is not supported.
Make sure to have the network-manager-openvpn network-manager-vpnc installed.

Forgot to say that the same connection perfectly works if run by command line

nmcli --ask connection up VPN1

And tested the same VPN with Netrunner 17.3 with KDE Plasma 5.9 it works. It looks like KDE Plasma 5.10 created this issue or Netrunner was not correctly build(To verify this need to try the same configuration on another distro with KDE Plasma 5.10).
