Hi @pm2662 

Thanks for your post!

My first thought would be to remove Deezer account 1 from Sonos and add it back on again.

Remove a music service account from Sonos

Add a music service to Sonos

If that doesn’t help, you can try checking Deezer in a Sonos app on another device (if available) and/or rebooting your Sonos devices and your router - unplug Sonos from power, turn off the router for 30 seconds, turn the router back on and wait for WiFi to become available again before turning Sonos units back on.

Finally, I would recommend contacting Deezer directly - the fact that Deezer account 2 works without issue might mean that there is something going on with account 1 that only Deezer would be able to resolve.

I hope this helps.
