Connexion impossible avec un VPN .

Bonjour , j'ai du toucher a quelque chose sur mon ordinateur , avant je pouvais me connecter a n'importe qu'elle VPN mais depuis peu je ne peu pu me connecter a un vpn . Je pense que le problème viens de mon ordinateur ou de ma box mais je ne sais pas par ou commencer a vraie dire , je ne suis pas vraiment orienter vers le réseau .
Vpn essayer depuis mon problème :
Cyberghost , Openvpn et encore bien d'autre que je n'ai pu en tête .
Pour l'instant la seul chose que j'ai touché c'est d'avoir remis les paramètres par défaut de ma box .
J'ai un rapport de openvpn :
