Wont connect.

[Pallzdani]

So I tried logging into today and I was at connecting for a long time (cata client) then 'Unable to connect, if the problem persists contact technical support'. Thought maybe the server was down, so I tried a different cata server, nope same thing. Tried your wrath and another wrath server, same. Then I tried retail and I was stuck at 'Success' and that was it. I flushed my DNS, restarted my Modem and disabled my firewall and still nothing. Was fine last night and nothing on my pc has changed, any ideas?

Edit: Recently updated to 6.2 on live, possible that has some conflicts?

Try power cycling ur router.

Note: If your modem has a battery backup, you will need to take the battery out or use the reset button on the modem.

Shut down all computers connected to the modem/router.
Power down/unplug the router if you use one.
Power down/unplug the modem.
Allow to sit for 60 seconds, unplugged.
Turn on the modem, and allow it to completely boot up until the front panel connection lights show a steady connection.
Turn on the router—if you have one—and allow it to completely boot up as well.
Start the computer and allow it to completely boot up.

Powercycling did nothing unfortunately

Are you using an anti-virus beside Window's firewall? If so try disabling it for a while and try again.
Also delete ur Cache folder if you didn't already.

Yeah I use AVG and that was the first thing I tried and cache was also deleted, gonna try another powercycle but leave it for around 10 minutes.

Edit; Okay nevermind, it just all randomly started working again O.o My ISP might of done something dodgy

Having the same issue, been trying to figure it out all day.
After logging in, wow hangs at "success".
If I press cancel or escape, it says "fetching realmlist" and hangs

I've deleted cache and wtf.
Flushed DNS (I've been using Google DNS for as long as I remember)
turned computer and router off for 5 minutes and turned them back on.
Still nothing.

Please help

Edit: I fixed it. Turns out it's my ISP. Guess I made the right decision in scheduling a cancellation/move to another ISP by the end of this month
