Speakers work but not visible on the app

 Hi @DDear, 

Thanks for reaching out to the Sonos community and for letting us know about your concern.

Let me suggest the next troubleshooting and see if it works for you to help you connect to your Sonos system.

1. Check the LED light
   • Press the play/pause button or join button on your Sonos speaker. 
   • Note if and how the LED responds. What is the light color? Is it solid or flashing light?
2. Put the player into a Hardware Diagnostic Mode
   • Press and hold the play/pause and volume down buttons or join button for 10 seconds. The LED light will turn Red.
   • Once in Hardware Diagnostic mode, please note the LED light pattern. (i.e. Solid Red, 11 White Blinks, Solid Orange, Solid Green, 4 White Blinks)
   • Press the play/pause button or join button to exit Hardware Diagnostic mode.
3. Open the Sonos app and connect to your existing system
   • Note: Please make sure that your mobile device is connected to the same network as your Sonos.
4. Use another mobile controller to connect to your existing system.
5. Sequential reboot to refresh your network and all your Sonos devices connection.
   • Unplug your network devices (modem, router, any wireless access points on the network) from the power and wait for 60 full seconds before you plug it back in.
   • Once the router is back online, unplug all your Sonos devices from the power. Please wait 15 seconds before you plug back them back in.
   • Force close the Sonos app from your iOS or Android device.
   • When the status light on your Sonos speakers are solid white, get back on the Sonos app and check if you're connected.

If you're still unable to connect to your Sonos system, I recommend contacting our phone support team to further look into this. Please let me know if you have any further questions or concerns, we’ll be glad to assist you.
