First post and such Anyway, just started this and because I’m cheap, I blew my daily instance spawn and because I just had to blow £300 on a new washing machine (timing!) I decided to continue with my own Linux machine and use the OpenVPN file supplied by the site (academy.ovpn) to access the box I needed. Except, it doesn’t work as-is and bombed out with the error: -
