Xbox 360 lets me sign in 1 out of 100 times I try.

When it does I can be on for seconds or hours. 90% of the time it is minutes or less.

I have an Ethernet cable running to the 360. When it works it works.

2 other Gamertags work every time.

I have tried subscription recurring off and on (it was always on, btw).

I have tried changing the avatars (both old and new).

I have deleted the system updates (X, LB, RB, X, LB, RB, X, LB, RB or whatever it is).

I have deleted my Gamertag and redownloaded it (this sucked because it took like 50 attempts to get online to be able to do it).

I have checked for security concerns and activated 2FA but disabled it once I confirmed it was not a fix (https://support.xbox.com/en-GB/help...in-security/something-wrong-microsoft-account).

I have power cycled the console.

I have checked my internet connection (https://support.xbox.com/en-GB/help/hardware-network/connect-network/xbox-360-network-connection).

I do not want to reset my console because I can rarely get on to redownload my hundreds of digital games. On Xbox One X and Xbox Series X the 360 backwards compatibility works most of the time but once in a while I get this error there, too. Don't want to reset yet if this may be tied to my profile not system. Can do this as last resort.

I have done more and I am forgetting, so any advice you give, I may have tried and will share.

I truly do not understand wth is going on.
