Plex DLNA Error

I want to use DLNA with Plex but unfortunately it doesn’t work. Here’s the content from Plex DLNA Server.log:

Latest Plex update installed. What could be the problem? Thanks.

Hi @midnightmarauder,

Please refer below link to check DLNA Media Server not detected:

Thank you, but I was talking about the DLNA server option in Plex, not Twonky.
