Can't connect suddenly

Hi guys its my first time on a private server.
I downloaded 3.3.5 old models,via the link provided on top via torrent.
I was able to connect and make a character all good.
Now i want to play again.
I type my ID and password,but it takes a while until it says.
Unable to connect please go to (blizzard official site)

Im lauching directly via WoW.Exe.

realmlist.wtf is correctly set.
Run as administrator didnt work.

Any more ideas?

SOLVED Adding a Exception Rule on Malwarebytes antimalware to WoW.exe allowed the client to connect properly.
It didn't require that before so i wonder what changed..
Well Thanks //can be closed
