cant join the same server as my friend

[Kyotoem]

I have played OP GOLD Veteran server on Black ops2 Zombies. I can connect but my friend can't connect to the same server, we are in the same Lan-Network. As Usally when me , my friend and my sister play , my sister have the same issue ( always Connect to server , or Joining game session ) or Downloading game details or smth, ) .
