Sometimes, I like to use Logitech Media Server (LMS) in addition to the Sonos app to control my Sonos devices. I have Sonos Move and a Sonos Play 5 (2nd edition). 

I installed a plugin in LMS called “UPNP/DLNA bridge”, so I can use desktop LMS and an app on my iPhone called Ipeng to control non-Squeezebox devices, including my 2 Sonos devices.

After installing the bridge plugin, I was able to initially see both my Sonos Move and my Sonos Play 5.

However, after about an hour, the Sonos Move disappeared from the list of available devices in LMS. What’s strange is that I can still view Sonos Play 5 and my Samsung TV (in addition to my Squeezebox Boom and Squeezebox Radio) in LMS.

When I open the list of plugins, under the list of "Players currently in the configuration file", the Sonos Move still is listed. I've tried hitting the "restart" button next to "Start the Bridge" but didn't work. I also tried rebooting the Sonos Move too. I can view both Sonos devices in my Sonos app, but again, I cannot view the Sonos Move in the LMS server, nor in my iPeng app which I used on iOS.

If there is anyone familiar with LMS and this plugin, I’d appreciate any troubleshooting suggestions. Thank you.
