unable to access the game since yesterday

hi,

since yesterday i can't log in to the game. having the message : unable to connect, please try again later.
my internet connection is working very well.

Best regards.

There's been many threads about connection issues, did you try solution(s) from those?

Go to your WoW/Data/enUS/ and open realmlist.wtf with notepad.

If it's something other than:

set realmlist logon.warmane.com

Change it to that.

Follow this guide and see if it helps: Warmane realmlist guide
