Hi @steveclarke1958,
Welcome to the Sonos community and thanks for reaching out to us. Looks like you're losing connection from your music library on your Windows PC that's why you're getting the error message "Can't find the server."
This happens if your Windows 10 PC is in sleep mode. When your Windows 10 PC goes into sleep mode, it turns off the display and it will temporarily disconnect from your network. In this state, if you're playing music from your computer, it will stop the music. When you wake your computer it will resume the services. However, in some instances, you need to reboot your computer or your network.
Let me share with you the troubleshooting steps you adjust the power settings on your computer.
- Open power options:
- Go to Start , select Settings > System > Power & sleep > Screen
- Go to Start , select Settings > System > Power & sleep > Sleep
- If you select Never, your display will stay on until you shut it down.
- You can also select a time frame in the dropdown.
- Click on Additional power settings > select Choose what the power buttons do > Power and sleep button settings
- When I press the power button: set to Do nothing
- When I press the sleep button: set to Do nothing
- Once done, start music playback from your computer and observe if you will get the same error.
I'd appreciate it if you can submit a diagnostic report from your Sonos system. Just include the confirmation number in your response so that we can look up the information.
Please keep me posted on the progress and let me know if you run into any issues for me to check.
