Suddenly (probably after latest PLEX upgrade) DLNA is no longer available on LAN. Has been working for several years now without problems. Server running Ubuntu 16.4
Tried disabling / enabling / reboot - but no change.
Suggestions on how to proceed debug??
Recommend you downgrade to a version which works with 16.04 because 16.04 is no longer supported ( expired April 2021 )
Thx. Have not seen any upgrade notes on changes to DLNA though, so cause is still unknown - and debug advice needed!
So - Ubuntu upgraded to 20.04LTS, Ubuntu firewall disabled, Plex reinstalled - same issue. No DLNA service.
What to do?
This was critical for streaming music to my Denon / HEOS setup - but luckily i found workaround as one of my HEOS devices support network-share setup…
