Toybox - Unable to use due to uni Proxy

Hi, I was just wondering if there was any way I could get round this issue:

I know it’s caused because I’m in university and therefore have to use a proxy to connect to the internet and Steam doesn’t support the use of a proxy (I’ve already contacted support and asked them if anything could be done, to which they said remove the proxy settings… -.-) so is there anything I can do inside or even outside of Garrysmod or would it be possible for this issue to be bypassed in a future update of Garrysmod?
I really love this game and it’s frustrating not being able to use this new feature…

EDIT: Nevermind, I’ve just been told it’s not possible so yeah, thread can be closed or whatever =/
