Everyone on the raid team was able to sign in no problem expect me. I kept getting this

<08:09:50> Trying to resolve hostname
<08:09:54> Trying to connect to server on
<08:10:00> Failed to connect to server

The server name is the same as everyone else. I even shared screens on Skype. It literally won't work. I have everything exactly how the owner of the server does. Help me? I ran it as admin. I uninstalled and reinstalled.. typed the server name a few different ways.. just cant' connect and its important for raiding. (obviously)
