Plex server has stopped reconizing my FETCH TV Box

Haven been using PLEX for several months but last week its stopped send movies to my Fetch Set-top box, my Plex library on my OS 10.15.1 has the movies in there but just not getting anything on the TV. I hand played around with a few setting in Plex and iuninstalled the Plex program re-installed but that didn’t help either>

I take it you’ve been using the Fetch’s “My Media Hub” to stream Plex media via DLNA to your Fetch TV?
If so… you might want to double-check the Plex DLNA settings.
From the related release announcement for Plex Media Server - #296 by Ridley version 1.18.1 (publicly released end of October):

NEW:

  • Set the DLNA server feature to be turned off by default. It can be manually re-enabled if required in Plex Web’s server settings (#10530)

I placed a tick in - Enable the DLNA server and its now working
How easy was that!
Why was it unticked??
Thanks for your help
Cheers
