Minecraft site not recognizing my game.

The migration from Mojang accounts to Microsoft accounts for Minecraft Java Edition has indeed been a point of confusion and issues for some users, me included.

Here's a few ideas to try:

1. Check Migration Status: If you've migrated your account to a Microsoft account, make sure the process was completed successfully. Look for a confirmation email.
   
2. Check Licences: Log into your Microsoft account and check your purchase history to see if Minecraft appears there. It might help you when dealing with support.
   

I've had this problem for weeks now, the billing site clearly shows my account is active but none of the *.xbox sites recognize it nor does my Xbox One.

I was told by this site that my modem is not recognize the box so going to call my service provider to fix it.

I get the same code and it doesn't recognize it. IT is happening on Minecraft when i try to load a game.

If the game is not showing as purchased on your account after signing in to Minecraft website, then the Minecraft system is not recognizing your purchase.
