siriusxm connection lost

There are several things I’d try.

First, remove SiriusXM from your controller. Wait a minute, then install it again.

Second, try rebooting both your Sonos devices, and your router. I’d do the router first, in case the speakers need to get new DNS data passed to them.

Finally, if neither of those work, I would recommend that you submit a system diagnostic within 10 minutes of experiencing this problem, and call Sonos Support to discuss it. Don’t post the resulting diagnostic number here, they get sensitive about GDPR.

There may be information included in the diagnostic that will help Sonos pinpoint the issue and help you find a solution.

When you speak directly to the Support staff, they have tools at their disposal that will allow them to give you advice specific to your network and Sonos system.

One caveat to that is the current issue as explained on the status page. You may want to do step two first, and wait to do the first once Sonos has resolved the issue indicated. 

Unfortunate I have completed all your suggestions and had a tech log in remotely to my computer.

Error messages kept coming in while I was working with support.

Today alone I have received over 50 error messages.

Support will be your best bet, but the issue may need to be resolved, first. Which is something support likely has no control over.
