Stucked in "logging in to game server"

Hi!
I'm stucked in "logging in to game server", can't log any server. I connected and played until two o'clock this night, then I closed the computer. Since this morning, every attempt of mine has been unsuccessful.

u are not only on this problem ... already clean CACHE and WDB but nothing work ...

Are you using the classic wotlk client or the one with improved quality?

Just classic one ...

I don't know what to do, reset the router, delete cache and WTF folder

ich hab genau des selbe Problem komm nicht in den Account und ein kollege von mir schon
