What information is showing in the “now playing” tile for that playback on the Plex server dashboard? Is the stream listed as Remote or Indirect?

Would you mind double-checking which exact version of PMS you have installed on the NAS? From what I can find, there was never a version 1.1.11 (just 1.1.4 and 1.2.1, which were both released in September and October of 2016 respectively; so I suspect there’s some typo or mix-up 
)
