How to fix can't connect issue.

I changed my realmlist from:
set realmlist logon.warmane.ru

to
set realmlist logon.warmane.com

Apparently the russian server is down.

Works make sure you change the file from read only so you can edit it

I want to expand on the above solution for players who are unfamiliar with what to do.

Locate your Wotlk3.3.5 folder and go to the folder "Data," then go to the only folder called "enUS." Inside the enUS folder look for a WTF file called "realmlist." Rightclick on the realmlist file and click "properties," then uncheck 'Read-only' and press OK. Then open the realmlist file with notepad and you should only see one single line that reads: "set realmlist logon.warmane.ru." replace the 'ru' part of the line with 'com' -- save the file and your login should work :)

Thank you, it worked for me.

How many Server's are there?.......

thanks guys its working now.... how come it was changed to .ru when i hadnt altered any of the files?
