Also try to Turn OFF firewall with app like http://www.binisoft.org/wfc.php (Which I personally use and recommend due the very low footprint).

Which version of MediaMonkey and what App on the tablet?

I am trying to control my music from my tablet but continual receive an error that "Server inaccessible. Searching..."

I can see all the playlists and tracks but whenever I go to play any it displays the error.
I can play tracks straight from the NAS but was wanting to play playlists and add tracks from the tablet.

turned the firewall and AV off on the PC but no joy. I can see the tablet in the sync section within tools on the PC too

Setup:
Desktop PC, Windows 10 with Media Monkey installed
Sinology NAS DS215j where the media is stored.
Cambridge Audio Magic streamer (Audio out)
Samsung Galaxy Tab S 8.4" Tablet (to control music)
