Unable to connect to PRIVATE SERVERS

Hi,

Friday I got the game from the magnet link (3.3.5 and 4.3.4), but I was unable to conect at any of those. I did a lot of things like open ports 3724 and 1119 in mi laptop and my router, shut off the firewall and the avast, but still the game stops at some point. I can see the list of realms, but that´s all.

Yesterday I download the official client, just for checking, and I was able to conect,...

So, what´s hapening? I can conect to retail, but not to warmane or any other private server.

Can someone help me?
