[2020] Error Code [6-0x00001000] Xbox One

Thank you for sharing your experience with us. If you have not done so already, you'll want to start by clearing the cache on your system. To do this: hold the power button down for a few seconds before shutting the system down and then you'll want to leave it unplugged for two minutes before starting everything back up again. Then, since you've already restarted the router and modem, you'll want to perform the steps listed here and have your internet service provider perform the port forwarding portion for you as this may be difficult to navigate on your own. You'll want to have the article we provided available when you call them though so that you can read them the UDP and TCP numbers listed. This should help improve on what you're experiencing, but if it doesn't, share a screenshot of the ports you've opened on your router and an updated account of what you're experiencing with our team so that we can check this out with you from here.

Hi GalaKnight

Further to what UbiKoality enquired about your connection, this error code usually means that the connection time with the matchmaking service has been exceeded.

I start matchmaking, wait about a minute and then get the error. I have confirmed that if I remove all my additional accounts from my Ubisoft account (All, and I do mean ALL of my account except for the Microsoft account, I am able to match-make without any issues. But if I want to play any Ubisoft game on any other platform my Xbox copy of Rainbow Six: Siege will stop working.

So I know it's the profile but this is a huge hassle.

Thank you very much for this information.

This is of course not intended behaviour, but we will use the answers we receive from players to find the root cause.

All the best!
