Can't log into chaos

[Tidal]

I can get into every other zone, apart from Chaos, which I was just in yesterday for league play. I don't know if it has anything to do with this or not, but I travel for work and I've been out of state for about 3 weeks, now I'm back home and my isp is different. Regardless my connection is fine, but chaos won't let me in...it just tries and eventually does nothing, then gives me a crap error msg.

Can someone correct this?

Thanks,

Tidal
