My Sonos is connected to the router using an Ethernet cable and the system will stream music and has an internet connection.
The thing is it won’t connect to certain parts of the online services: for example, I cannot submit diagnostics, I cannot use third party controllers that rely on the Sonos web api, the Recently Played tab in My Sonos does not update or populate with music.
I have tried contacting Sonos tech support and we switched over to the ISP supplied router. This solved the problem though we don’t know why. As soon as I switched back to the D-Link the problem reoccurred. Unfortunately the ISP router is not great in other ways and so I would prefer to solve the issue with my decent router.
The system previously worked flawlessly so obviously something has changed. I have a Sonos connect which is hardwired to the router, plus three Play:1s and two Sonos Ones Gen 1.
If anyone has any bright ideas about what could be causing the issue I’m stumped!
