For a couple of weeks ago I've bought a Nvidia Shield TV which primarily is used as a Plex server. Even though there's a connection to the server, Plex keeps saying my media is "Unavailable". This is a problem on both my Nvidia, but also on all of my clients. My media is stored on my NAS which, of course, is connected to the Nvidia. The only way I can help the "Unavailable" problem is by dismounting the NAS from the Nvidia in Nvidia's settings and remount it afterwards. After this procedure is done I can play all of my media, but after a couple of hours they get unavailable again.
The Nvidia and my clients all have the latest software update.
Have any of you experienced this?
