Error 1001 and 1002 when using the music library

The Sonos app can show Error 1001 or Error 1002 when your Sonos system is having trouble connecting to the music library on your computer or NAS drive. These errors usually occur when the computer or NAS drive is either offline or having trouble maintaining a reliable connection to the network.


If you see Error 1001 or 1002 when using your music library:

  • Check your computer or NAS and make sure that it’s powered on and awake.


  • If your music library is stored on a computer that’s connected to WiFi, make sure it has a strong wireless connection to the router.


  • A firewall can block Sonos from properly connecting to the computer. If a firewall is installed on your computer, make sure it’s configured for Sonos by following these steps.
