Questão openvpn funciona no terminal, mas não no networkmanager


Eu estou tentando fazer com que minha conexão openvpn funcione. Eu uso uma chave estática deste tutorial: ligação

Quando me conecto via terminal sudo openvpn --config client.conf está funcionando e eu recebo o ip da vpn.

Mas quando tento conectar via NetworkManager, recebo erros.

Meu sys.log de Mint (Sylvia):
