Stream drops, then nothing resumes
I've been running into an issue the past few weeks where shows and movies will randomly just stop playing when watching on my Shield. It tells me it couldn't reach the server. It then is unable to resume on the original player, but will also fail new playback on the web, iOS, etc.
Restarting the server machine completely is the only thing that allows playback to resume, and even that can be spotty. If I manually restart the server from the command line, it takes a very long time to shut down, but still won't play anything when it comes back up.
