Xbox connection issue on PC

Hi! I'm Rostom, an Independent Advisor. I will be glad to help you here.

How did you get that error exactly? Do you get the error right away when you launch your Xbox app?

How about your other apps or services on PC, are you able to access them online just fine?

Make sure that your Windows is up-to-date and also get all the updates from the Microsoft Store.

Do you have a PC/Laptop that you could connect on the same wire that you were using for the Xbox? If you can do that, and test to see if the PC has the same packet loss issues. That would tell you if the issue is more likely with the Xbox, or with the
connection.

Are you connecting directly to the router, or is there a wall connection between your Xbox and the router? If there is a wall connection, then the wire in the wall could be the issue.

Same thing here, today I've been completely unable to log into GFWL in SSFIV, Arkham City, Arkham Asylum or Warhammer Dawn of War 2 on PC. Was working just fine yesterday, and I've not done any changes to my system. I hope MS is at least aware of the issue.

Edit: Should add, signing in on GFWL Marketplace client outside of games works just fine, its just in game I can't log in.

Here guys...They know there is a problem so at least they are working on it.Here is the correct link

Greetings all!

Just want to stick my head in here and inform everybody that this part of the forum is solely related to the Xbox 360 console and connection to Xbox LIVE. I would recommend all concerned to address their respective issue here instead:
Games for Windows - Connection / Networking

Good luck! And a great weekend to all.
