My plex server unexpectedly stopped working today. I have two rokus that usually are used to watch content. Though I will occasionally watch through the app on my PC. I have been running this setup for nearly two years. My family was able to view content on one of the rokus yesterday (2/21/17). Today (2/22/17), however, they were unable on either. They got a message saying that there was no server found. When I tried to connect to the server through my PC the web app loaded but said that the server couldn't be found. I logged on to the server and checked to make sure that the plexmediaserver service was running. For good measure I stopped it and restarted it. That didn't fix it. I then rebooted the server. No avail. I downloaded the newest version of PMS (1.3.4.3285) and installed that. It still doesn't work.
These are the versions of plex server that I have used:
plexmediaserver_0.9.12.4.1192-9a47d21_amd64.deb
plexmediaserver_0.9.15.6.1714-7be11e1_amd64.deb
plexmediaserver_0.9.16.5.1966-81a3bf0_amd64.deb
plexmediaserver_0.9.16.6.1993-5089475_amd64.deb
This was the one I was using when the problem started:
plexmediaserver_1.1.4.2757-24ffd60_amd64.deb
I installed this one after having problems:
plexmediaserver_1.3.4.3285-b46e0ea_amd64.deb
I am running a headless (console only) installation of ubuntu server 14.04. It has a static IP. I manage the server remotely from my Windows 10 PC with Putty and manage plex with the web app. All of my media files have read/exec group permissions and plex user is a member of the group. Like I said it has been working for nearly two years. I hadn't logged onto the server for several weeks. I attached my log files.
