Thanks, this worked; much appreciated,

Hi @Tonyk57, welcome to the Sonos Community!

I don’t see anything in our resources about an error 500, but generally this is a timeout error with many services, so it’s likely the same here. 

I would recommend the following steps:

• Try a different controller, such as another phone or tablet.
• Reboot the controller you’re trying to add Qobuz with.
• Reboot your router and Sonos speakers.

If you’ve tried the following and still can’t add Qobuz, then I’d suggest reaching out to our support team for further troubleshooting, as they have the necessary tools to assist in resolving this with you.

I hope this helps!
