Please open the Alexa App and Disable then Enable the Sonos skill, as a first step.

There are several possible causes for the error message "Sorry, something went wrong" on your Sonos One with Alexa voice assistant. Here are some troubleshooting steps you can take to address the issue:

1. Check your internet connection: The Sonos One with Alexa requires a stable internet connection to function properly. Make sure your Wi-Fi connection is working and that your router is not experiencing any issues.

2. Restart your Sonos One: Sometimes, a simple restart can resolve the issue. Try unplugging your Sonos One from the power source and plugging it back in after a few seconds.

3. Check for software updates: Ensure that your Sonos One is running the latest software version. Open the Sonos app and go to Settings > System Updates to check for any available updates.

4. Disable and re-enable the Alexa voice assistant: Go to the Sonos app and select the Sonos One that is experiencing the issue. Navigate to Voice Services > Alexa and disable the Alexa voice assistant. Wait for a few seconds and then re-enable it.

5. Reset your Sonos One: If the above steps do not resolve the issue, you can try resetting your Sonos One to its factory settings. Press and hold the Play/Pause button and the Volume Up button simultaneously until the light on the Sonos One flashes orange. Release the buttons and wait for the light to flash green.

If none of these troubleshooting steps work, you can contact Sonos customer support for further assistance.
