It does seem to me to be an error output at the TV OS level..but the TV displays NO network issues with anything else (youtube, netflix etc.) and no other device on my network has plex connection issues. Also, if I use the TV to stream anything through DNLA from the same Plex server it works perfectly.
I seem to get these in the console when the -337 is displayed:
[CompanionProxy] player ffyjop4r2op6vl1brtemtgf2 was last refreshed 10 seconds ago
This shows up in console right when it happens.[Plex Media Server
Failed to stream media, client probably disconnected after 63819152 bytes: 104 - Connection reset by peer
