openvpn funktioniert im Terminal, aber nicht im Netzwerkmanager

Ich versuche, meine Openvpn-Verbindung zum Laufen zu bringen. Ich verwende einen statischen Schlüssel aus diesem Tutorial: Link

Wenn ich mich per Terminal verbinde, sudo openvpn --config client.conffunktioniert es und ich bekomme die IP vom vpn.

Wenn ich versuche, über NetworkManager eine Verbindung herzustellen, erhalte ich Fehler.

Mein sys.log von Mint (Sylvia):
