Can't play any Xbox 360 games on my xbox series X

I have the same problem, I can't connect to Xbox Live on the Xbox 360 games (on my xbox serie x) since few days 🤔 I precise I don't have any problem on the Xbox serie X games, I have that only on the Xbox 360 games.

My internet is perfect too (I live in Belgium)

So I can't even play the game on my Xbox series X controller without the guitar also I can't play the disc version on my Xbox series X

Hi,

Where did the Xbox 360 games come from? Another Xbox 360?

If they were downloaded via an Xbox One/Series console you can't play these games on an Xbox 360. Firstly the drive wouldn't be configured for an Xbox 360. Secondly, Xbox 360 games downloaded via an Xbox One or Series X|S are actually 360 games that have been converted to run on an Xbox One, they are no longer native Xbox 360 games.

Hi,

I did all the 4 fixes mentioned before i made this post. If it makes any difference this only happens when playing SERIES X/SERIES X Enhanced games. If I play a XBOX ONE or XBOX 360 game it will remain on without an issue

I believe what is meant by "full" is that all current gen games and any games that were already made available via the backwards compatibility program (Xbox 360, original Xbox) will be playable on the Series X. So basically "full" means everything you can
currently play on an Xbox One right now you will be able to play on the Series X.

But those 360 and original Xbox games that are not currently backwards compatible still will not be playable on the Series X. That's due to licensing issues with the older games.
