Have you called Sonos support?

Without more information, I’d be looking at the account on www.Sonos.com to make sure the address was set properly, then be looking at VPNs, port blockers, or virus protection that might be blocking Sonos to be reaching out to the appropriate server to get the data. 

But honestly, the first thing I’d be doing is calling support. 

Ok I’ll call. I’ve had my Sonos system for about 5 or 6 years now and the ap has always worked seamlessly, never an issue and nothing has changed. I can airplay from my phone but the services I’ve put into the Sonos ap no longer work. Frustrating 

I hear you. I’m convinced there’s a bug in their db software that changes the associated mailing address very occasionally, and very randomly, which changes what is provided to you in the controller, but it’s super hard to prove ;)

The CS rep should be able to see your account, and confirm whether I on the right track, or way off base. But they should be able to resolve the issue for you, either way.
