Smart device Apps continue to work perfectly, so there can’t be an issue with my WiFi, my desktop doesn’t. I’ve gone through all the troubleshooting variables turned off the modem, unplugged my broadband connection and all devices several times, checked ethernet cables etc.

I use both the Sonos S1 App and Spotify App on my iPhone and iPad most of the time, and I have no problems connecting using these smart devices. I can’t honestly said when this started as I’ve only just noticed it in the past week. The S1 controller connects the first time after a start-up or restart, but if I quit, or the computer goes to sleep the app can’t connect back to the system, Spotify lists all my devices but these are always greyed out and cannot be used. System has been working fine up until recently, but I now have an issue connecting to my Sonos system from the S1 controller and Spotify from my iMac (High Sierra 10.13.6). I have a hardwired Connect, and various WiFi speakers (Sonos 1, Play 3 and Playbar).
