hey there Zephyr0260,

Thanks for reaching out to the Apple Support Communities! for the error you're seeing on your Mac in the Music app, we recommend to follow the steps outlined in this helpful article If you can't connect to the App Store, iTunes Store, or other Apple services.

In addition, you can re-authorize your Mac to see if that helps. To perform this step, please open the Music app, navigate to the menu bar and select "Account" > Authorizations > Authorize This Computer.

Please keep us posted with the results.
