Plex asleep on Nvidia Shield
I have a new Nvidia Shield running primarily as a Plex server ("Shield Android TV") with all updates.
My Plex data is on a NAS. Everything works well. Fixed IP addresses and hardwired.
The problem is that after a few hours not being used, the Plex server goes to sleep and cannot be woken up by an external device such as a pc on the same network.
To activate Plex I have to go to the tv which is directly attached to the Nvidia Shield and access Plex from there. Once "woken up" again, everything is back to normal.
I have tried making all appropriate settings to the Nvidia Shield setup to stop that sleeping and also to the Plex server. I have even tried setting Plex to scan library every 2 hours as an attempt to keep it alive.
The inevitable message when trying to access the Plex server after it has "gone to sleep" is "The server Shield Android TV is unavailable".
If I go to the tv which is attached directly to the Nvidia Shield, the Shield is on and working. Selecting the Plex app will only show the news feed and none of my libraries. The Plex app is working but the Plex server part of it is off.
I need to select something like a recent part viewed movie to "wake up" the server. I can only do that directly on the Nvidia Shield, not from a remote pc.
How can I keep the Plex server on my Nvidia Shield available on demand 24 hours a day?
