Cant access Twisting Nether on my account

[Misthea-draenor]

Hi, we are many who has this issue and it’s not related to a particular realm. Basically we are able to log in only to realm we logged on last time we were online before update.

check this:

Retrieving realm list and character not found

Been having the same problem all morning. Cannot log into any character on Kazzak, But perfectly fine logging into any other server. Have followed the troubleshooting guide but nothing worked.
