Cant log

I cant log on my acc since yesterday,it shows me that server is down.Already did all with realmlist.What to do?

do you still have this problem?
I am able to log-in to both Cata realms, check you are using the correct realmist:
set realmlist logon.warmane.com

If possible provide a screenshot of the error message becuase " it shows me that server is down" is too generical

No,Im fine now.Just restarted comp and now works.Dont know what was the problem.
