Yes i am using that link I only have access to the internet from my local Junior college. and i doubt they block the usage of cpanel since i can access HG cpanel from here.
Appending /cpanel doesn't work any more.
If your college has a filtering proxy (my school does) it kills any non-standard ports, such as the cPanel port. I can't access cPanel from school for that very reason.
I know our school's proxy literally kills anything other than port 80, which is http, and a few in the 10,000 range. I don't think they realise I use higher ports than they think to block for VPN and remote desktop.
Noooooo.
All mine.
Anyways, yes, it's likely your college's network is causing the problem.
Have you considered getting a mobile broadband dongle or something similar?
