Currently whenever I attempt to connect to any server I get booted back to the lobby with the message "connection to the host has been lost." Any idea why this issue is occurring please?

i have the same problem and i would like some help too!!

Guys, you don't mention what platform you are running and unfortunatly, Ubisoft feels that it is less confusing to have all platforms merged into one!
(Even though they are the only ones that think so)

That does make a difference in the solution and maybe will help with an answer!

Hi, i'm also currently having the same problem "Connection to Host Lost" when I try to join a game.

I'm a PC user, windows vista 32, top range nvidia card etc.

Few interesting points: I use a BT home hub, however two other people on my hub can play the game fine, while I can't.

I have McAfee security Centre, though have allowed acess for the game and all it's ports, still no dice.

After about a million attempts I DID in fact manage to get in a few games, but now I can't again.

Someone told me it might be something to do with Punk Buster kicking me for some reason, but i'm a noob to it, and never really played online before.

Please help!
