You can follow my manual https://airvpn.org/topic/20303-airvpn-c … de-tunnel/ with necessary modifications. It is topic of General Discussion, not Community Documentation.

sorry wasnt sure where to post
followed your guide changing parts for cyberghost  ovpn file etc
now getting Options error: Unrecognized option or missing parameter(s) in /etc/openvpn/openvpn.ovpn:18: explicit-exit-notify (2.3.6)
but their is no explicit-exit-notify in openvpn.ovpn
driving me nuts started fresh 3 times now same result even tried changing to openvpn.conf same result also redownloaded zip from cyberghost 3 times
did some googling not much info just advise to remove explicit-exit-notify
but isnt in etc/config/openvpn or etc/openvpn/openvpn.ovpn

ok tried again and here is what ive done and the log at end driving me crazy

Bring content of your OpenVPN configuration file /etc/openvpn/openvpn.ovpn, there should be option explicit-exit-notify. Remove private data like login, password, crt, key files, of course.

Comment following option:
