Any firewall or ad-blockers that might be causing the connection to fail?
Hi, thanks for the help but in the end what helped me was restarting the sonos ultra using the following procedure: 1. unplug it from the power outlet 2. press and hold the bluetooth button on the back, while reconnecting the power cable, release the bluetooth button only when the light on the front starts flashing orange. Then I just did the complete connection settings again and the sonos ultra works, thanks for the help.
