I recently bought a QNAP TS-231 to house all of our TV shows and movies on a NAS that's accessible throughout our LAN. Previously I had a Mac mini with an external hard drive but it was time for a change after it started causing me some issues.
I have all the media transferred in shared folders and have installed Plex on the QNAP. Plex seems to run well after I added the shared folders for each of TV shows and Movies, it updates the database, etc, grabs all the metadata, and is accessible across the LAN, over WiFi on various devices such as the Roku3, Android phone, iPad mini, etc. The problem happens at random intervals where the media server simply disconnects. When trying to access it, I get an error that the "site" does not exist. During this time I check the NAS to make sure it's operating fine and it is.
The only way I've found that I could get Plex to work again is by going into the App Center on my QNAP, Selecting the Plex Media Server and setting it to OFF. After it takes a few seconds to turn off I then set it to ON and once it's back on, it works fine. Now obviously this is not an ideal situation especially if I'm not around and my wife is trying to watch something.
Anybody else experience this issues and how have you resolved it? Any setting and such that I should be looking at? I've looked through all the screens I can think of and can't find anything related to this.
