Connecting...

After I log in and click 'Duel', I get stuck on the connecting screen. It'll sit there for as long as leave that tab open, with no progress.

I've tried different browsers, turned off my firewall, and even made a new user flush of any settings or files, and I experience the same results.

DN works at home. I'm on a university network now. Is there any way I can get this to work, or am i just stuck?
