Sample app PhotoShare not connecting

Hello, I tried implementing the sample app * PhotoShare

Receiver app is running on Samsung TV UE43TU7172UXXH.

Sender app has this code when initializing:

var search = window.msf.search();
...
search.start();

but it never enters breakpoint inside
search.on('found', ...

So the app never gets the list of available receivers.
I tried running sender app from my PC in Chrome (both PC and TV are connected to the same network) and Chrome on my Samsung phone.

Any help appreciated.
