I can login to the account server.

  I can open the community updater.

  I can ping over the server 217.79.190.136

  I can open the server 217.79.190.136 (as a web server)

  I can not join the game in any server in multiplayer and it says there is a problem with your connection.

What is wrong?
I called my ISP for help and they answered that there is nothing they can do and it can possibly that my IP is banned.

Can someone help me with that because it is getting old.

note!
I can access the online server using a vpn, but you know it has High unstable ping.
