Cannot log in to Microsoft Sudoku--no Xbox connection all week

I have tried all the steps in that document several times, with no change. I still cannot get the software to connect to Xbox Live. It is weird, i can log in from Solitaire and Mahjong, but i cannot get Bingo, Sudoku, or Enter the Mind to log in.

The error message says "Something happened on our end. Waiting a bit might help. The error code is 0x80190191, in case you need it." This has been happening for the last 24 hours.

This is on a Windows 10 laptop PC.

I am having the same problem loggig oto Microsoft Jigsaw. I can log on to Microsoft Solitare, Sudoku and Mahjong as well as Magic Puzzles. I log into all with my Microsoft log in and on the main Microsoft site. Please help.

Same thing here. Yesterday all was fine. Today everything is gone and I can't connect to Xbox, so my entire history is now gone.

The basic problem seems to be (as identified in an even more recent post) that Sudoku cannot link with the Xbox server, even though Solitaire and other games running on the system have no problems and you can link to your Xbox profile from the same 'error
tile' that is telling you that Sudoku can't!! Why does Microsoft keep breaking this game?!!

I have the exact same problem. I have uninstalled & reinstalled with no result. I can click on the green xbox button in the upper right hand corner of Sudoku and be signed into xbox without any problem. I can exit Sudoku, sign into xbox, and punch the
"play Sudoku" button, which initiates Sudoku, but Sudoku still says it cannot connect to xbox.

I have on a couple of occasions seen a message momentarily when I first initiate Sudoku that seems to imply that this is a new version of Sudoku and you don't have to sign into xbox to play it. But then I don't have any history
of my playing Sudoku over the past 4 years. The message disappears before I can study it. Is there a new version of Sudoku that is causing my problem?
