Can't connect to Xbox Live Party

I've got this problem too, and it only started happening this evening randomly. I was even in the party with this friends when it happened and we BOTH have tested all the steps to sort out the error. This has happened for other friends too. So, it is obvious that it is a problem with MICROSOFT and not us. Fix this problem and stop putting it under the rug, by coming up low winded steps to waste peoples time, rather than dealing with the issue at hand.

I'll still probably get asked to check my NAT...

I have the same issue as everybody else here. I cannot connect with some friends when we could just the day before, I cannot join parties or game sessions, our internet is fine and dandy with open NAT. With this sudden change in performance and everything Microsoft has told us that will fix this issue and has not...I find this a gross insult to my patronage...

Either fix this widespread issue or give all of your insulted costumers a refund for undelivered service!

You might notice that mods/"helpers" here are now ignoring this completely and just going into the smaller less posted topics. Clearly this isn't us and its you (sounds like a terrible relationship).

While I'm not mad at all, I find it rather insulting that my Ambassador status was taken away and would love to know why (after years in it). Is it because I'm posting that I have a serious problem that no one is helping with. Not a single person trying to help in these 3 months has contributed to fixing this, in the forums, phone or twitter. At least the phone support stated they  "were going to alert the mods". Before one of them comes in here and states that they HAVE tried helping us, think twice about that. They must take us for idiots to think most of us in this forum have not checked NAT, reset routers, modems, checked DMZ's, etc.

LOL Vash, couldn't have said it any better. Now it seems when you try loading an app or even a game that it tends to lag more and cause the party to crash.

reset your router if not call 08005871102 it is the free xbox support number
