Hey,
Just looking into this now. I'm not seeing any connections from you.
I just saw someone login to the TBC successfully, can you check your firewall is running ok ?
Also try "logon.covenant-wow.com" in the realmlist, both should work.
set realmlist logon.covenant-wow.com
set patchlist logon.covenant-wow.com
set realmlistbn ""
set portal eu
I just tried from my end and I saw your account pop up but invalid password so its working for me.
