First, you do not have to have TCP ports open, playing any Private Server does not require ports to be opened, or forwarded, unless you're directly hosting it off your PC.
Have you checked your Windows firewall? Perhaps run as an Administrator? Check your computer for Viruses perhaps? It could be an internet issue, so I would suggest running an internet speed test?
If all else fails delete your WTF folder located in your World of Warcraft folder.
I hope this helps.
