Medias can’t be played from shared database

Hi !

I got shared MySQL library stored on my Synology NAS. My main Kodi installation is running on windows 10 in the living room. Sources are shared through NFS (I have authorized every IP adresses) and everything is working fine on this machine.

Unfortunately, my Android TV’s installations in the other rooms are unable to play any medias. They are able to see the library, the seen/unseen status but nothing happen when I hit play…

In order to configure my Android TV’s installations I have created the advanced settings files without adding any sources, is that the proper way to do it ? Do you have any idea why the files cannot be reached ?

Thanks a lot !
