The error message indicates an authentication/authorization problem with the Microsoft account used for Minecraft, not with Windows or the Feather client itself.
When Microsoft account sign-in or access to a service is blocked or fails, it is usually because:
- The account or a specific sign-in alias is blocked or turned off.
- There is a sign-in or access restriction on the service side (for example, a ban or privilege issue for multiplayer access).
For Microsoft account sign-in issues, the documented steps are:
- If the error is about a specific alias being turned off for sign-in, use a different alias on the same Microsoft account:
- On the sign-in page, choose Forgot your username? and enter the alias being used.
- Use the code sent to the primary alias to see which aliases can sign in.
- Sign in with an alias that is not blocked.
- If the sign-in page shows a generic error like “Sorry, but we’re having trouble signing you in” for the Microsoft account:
- View the source of the sign-in page at
login.microsoftonline.com.
- Search for
HR= and note the numeric error code.
- Use that code when contacting Microsoft technical support for further troubleshooting.
If the Microsoft account itself is banned or restricted from multiplayer services, or if the problem is specific to the Feather client’s use of the Minecraft session endpoint, resolution requires support from the service that is enforcing the restriction (for example, Microsoft account/Xbox enforcement or the Feather client’s own support). That part is not covered in the provided documentation.
