Re: i cant join a party on MW3! why?!

Please run a network test on your console and report back any errors. This will be the start - In MW3 on the left side right above Welcome to  Call of Duty it will provide your NAT status.

And the Nat could be the problem all together.

i did that & my nat type is open. this problem just started, ive always been able to play in a party online. untill yesterday. Thanks.

im having same issues man, let me know if you figure this out please. my nats open and just started last night that i cannot join anyones party. i can search and play with everyone else, but it wont let me join my friends games

yep, same thing, i will let ya kno. it sucks!

It might not be your NAT settings. If you're attempting to join a party hosted by someone else, it might be their settings, in which case they'd have to run a network test and change some settings on their routers.

Maybe check your NAT settings? One of you could have some how ended up as a closed NAT and that would affect it.

yeah, thanks. but they can join each other by invite or by sendin the invite & i cant do either. they cant accept mine & i cant join them.

I'm having the exact same problem. It only affects Mw3. I'm able to join parties in Black Ops and Mw2. Microsoft, Activision, Infinity Ward.. whoever.. Fix this ASAP. I didn't spend $60 + $50 for elite (which also isn't working lol) not to make use of them.

it's a joke i can connect to my mates all over the world but not the ones in the town wot a JOKE... IF THE UPDATE ON MW3 HAS MESSED MY CONSOLE UP I WILL WANT THE MONEY FOR THE GAME AND A NEW CONSOLE ACTIVSION YOUR CRAP!

yeah, this sucks! 2 days straight now & i can talk & play with my friends......

Quick question for all - Does this happen in all games, or just MW3?

Just Mw3. I was able to connect and be connected to in Black Ops and Mw2

yeah, just mw3. i tried other games too. it seems like maybe it started after i started to waste my time & space on that elite crap that didnt work....love everything about the game, i just want to be able to play with my friends. still wont work, just tried again.

For people who are having trouble connecting.

Are you participating in the dashboard beta?

I have been experiencing the same problem as above on my console that is registered for the beta, but on my other console I am able to connect and receive invites with no problem.
