OpenPHT is not playing from Synology server

Hi,

I have one Synology DS416play server with 8tb capacity and 10 OpenPHT clients are there. I have installed plex media server in NAS server and OpenPHT in all my clients. I have added libraries first time for my plex server and the same libraries are showing in all my plex clients. But when i play any video from my app, it is not playing anything. It is just doing up, down, left and right moving from remote app. It is not playing anything. Kindly help me to solve the issue.
