If that does not resolve, then would need to see if we can capture packets between the transcoder and plex media server that come in through 127.0.0.1
Also you had debug logging disabled on the server - you would need to enable it and for transcoder issues would also need verbose logging - but that would mean you need to capture logs immediately after the failure as each log file may fill up in 5 minutes with verbose logging
Cool - OK. First thing: no updates available, windows is up-to-date.
Here are some log files - I kept a few extra ones just in case, but the issue occurs in Plex Media Server.2.Log at Dec 15, 2018 13:10:17.536.

The pcap file is really large (1.2G) really sorry… I’ve uploaded it to google drive though, it’s here: (removed)
[EDIT]: I’m no expert at PCAP files, but I think the issue might occur around 2426 secs. It’s almost bang on from the file creation date to the time of the logged error (which is 2432), and after 2426 there’s significantly less logging (ie from 2427 onwards).
