Mosaic can’t detect my Rossini Player out of a sudden

Hi, Mosaic could not detect my Rossini the whole day suddenly, tried to troubleshoot my lan network, everything seems fine, I can use Airplay on the Rossini, my music server connected to it seems fine too, tried changing lan cable and reinstall Mosaic still don work.

Pls advice.

First thing to try in these situations is to power cycle your Rossini using the rear panel switch and completely kill and restart Mosaic Control on your tablet / phone.

When you tried airplay was it from the same device that you use to run Mosaic Control?

Yes same device to operate Airplay On my mobile phone or Ipad.

Do u mean to off the main power switch on the rear panel? I tried that but did not work too.
