Error 27 occurs when one or more Sonos products is unable to reconnect to your home network following an update. The error screen will indicate which of your Sonos products is experiencing the error. Below are some common step you can take to resolve this error.


Close and reopen the Sonos app

Close and reopen any Sonos apps you're using. To close the Sonos app:

  • On Android, swipe up from the bottom, hold, then let go. Swipe up on the Sonos app.


Reboot your Sonos products

Reboot the product(s) specified on the error screen. Once you have rebooted those products, wait for them to reappear in the Sonos app and try the update again.


Move closer to your WiFi router

If possible, move the Sonos product experiencing the error closer to the router and try the update again.


Temporarily wire a product

If possible, temporarily wire the affected Sonos product to your router using an Ethernet cable, and retry the update in the Sonos app. If the update is successful, unplug the product from your router and return it to its original location.
