Won’t let me sign in on Xbox 360 live on my series x

Hi and thanks for reaching out. I hope you’re doing well. My name is John P an Independent Advisor and a Microsoft user like you and I'll be happy to help you.

Sorry to hear you're having a problem with your Xbox 360 game. Just a friendly reminder though that there are multiple reports of the same issue, however, there are no official announcements from Microsoft yet so in the meantime, we need to perform troubleshooting steps.

- Check for available console updates

- Test Network Connection

- Clear Alternate MAC Address

- Test a different network connection (e.g. hotspot, wired connection, WiFi)

- Change your DNS connection by going to your Settings > Network Settings > Advanced Settings > DNS Settings > Manual > and manually changed the primary DNS to 8.8.8.8 and the secondary DNS to 8.8.4.4 and then restart your console.

Bro my Xbox 360 is throwing me the same code that you have, I did everything you did an now I can’t even access my Xbox live account, it won’t let me sign in

I am having the same issue and same error code (80151912) when I'm running the Xbox 360 emulator on my Xbox series X.

I can sign into Xbox live on my Xbox series x but not on the emulator running the Xbox 360.

It says I’ve been suspended from Xbox live and I won’t be able to sign in when I’m unbanned but the only problem is I’m communication banned and it should have no effect on playing games and it’s on all my Xbox 360 games I play in an Xbox series X but the problem also happens on my Xbox one s and I am not the first user on this xbox. Please fix this as soon as possible.

Also, I’m having the same issue playing my 360 games on my Series S, my Xbox Live account won’t download onto any 360 game on my Series S.
