Cannot login(2 accounts so far)

Hello. I have a login issue here. Every time I enter my info username and password, I get a message saying "Unable to connect, please try again later...".
Also files: "WTF/Config.wtf" has its realmlist set to "logon.warmane.com", and "data/enUS/realmlist.wtf" is set to "set realmlist logon.warmane.com".
I have even created another account to make sure its not an issue with the username or email, but it didn't work. Also I don't have an antivirus(besides windows defender) so I doubt the connection is being blocked.

Update: I fixed my problem. Turns out the text editor didn't save the realmlist when I changed it. All this time i was attempting to login to "logon.warmane.ru", while it should have been "logon.warmane.com"
