Hi @Tclarke.

Thanks for reaching out and welcome to the community! Let me help you figure this out.

This error can occur when Sonos is unable to find the computer or device hosting your music library, the attached article will provide some common steps you can take to resolve this error.

If the above advice was followed and the issue persists, please submit a diagnostic report through the Sonos app on the computer and provide us with the confirmation number, so I can see if there’s anything else causing this issue.

Let me know how that goes.

Thank you for your response, but none of the instructions have worked.  The message indicates “The computer TOM cannot be found.”

I have submitted diagnostics, and my verification number is 1713749715.

Thanks

UPDATE!  My Music is back!  Please disregard messages, and please don’t enter my system or change anything.  Thank you!

SONOS appeared numerous times in my apps allowed through firewall.  I deleted many of the duplicates, and re-started my computer.  Thanks again.
