Why can't I create a private session?

So I can’t play multiplayer due to the “failed to get match server list” bollox
Thought I’d host a private online game, and what do you know? that doesnt work either ffs … “Failed to create game session” every single time I try.
What the hell are you playing at? , the online side of this game is just broken, I have no trouble with any of my other games at all , just this piece of crap.
Why on earth will the game not let me create a private lobby ?, any answers ?
