Hi @fregor77, welcome to the Sonos Community!
I’m sorry to hear that you’re having issues playing to Sonos through Spotify Connect. I’ve given this a test on my system and I was able to use both my phone and computer to cast to my Sonos.
A recent update has added stability improvements for Spotify Connect, so I’d recommend making sure the Spotify app, Sonos app, and your Sonos speakers are fully up to date. If everything is running the latest firmware, then re-authorize Spotify in the Sonos app by heading to Account → Content Services → Spotify → Primary Account → Reauthorize Account.
It’s also worth rebooting your network and Sonos system as Spotify Connect will work through your home network. You can do this by powering off your Router → Additional networking equipment → Sonos speakers → and devices running the Sonos app, for around one to two minutes. Once they’re back online, try and use Spotify Connect again.
If the above doesn’t help and you still can’t cast directly from the Spotify app, then I’d suggest submitting a diagnostics within 10 minutes of Spotify Connect failing and then reaching out to our support team for further troubleshooting and assistance.
I hope this helps!
Thanks for reaching out. I’ve tried most options here:
- Sonos app and Spotify app has been reset/reinstalled
- Spotify account has bee reauthorised in the Sonos app
- All my network has been restarted (powercycled) (Nest Wifi + Google Wifi, Norwegian ISP Altibox + Netgear Switch)
- All Sonos devices affected has been restarted (powercycled)
- MAC adress for phone has been anonymised and reverted
- Checked updates for apps, and Sonos devices - 80.14.06 / 82.2-59204
The issue persists, so I’ll try and send the support some diagnostics
