Instalei recentemente o openVPN e configurei-o com meu arquivo client1.ovpn:

Quando eu faço o comando

Eu recebo este erro no terminal:

Eu também não consigo me conectar à internet enquanto o openvpn está em uso no terminal. Não é até eu acertar o crtl + c antes de poder me conectar à internet novamente.

Depois de ctrl + c, recebo esses erros também:

Eu tenho tentado encontrar uma resposta para essa pergunta no google já sem sorte.

O que está causando esse erro de "ERRO: o comando Linux route add falhou: programa externo saiu com status de erro: 2 "

e também o que está me causando a não conseguir se conectar à internet durante o uso. Obrigado.
