This issue seems to come up anytime I try to play an HEVC movie/tv show from my Plex Server. The error I get is "Conversion failed. A required codec could not be found or failed to install.".
I have gone through all the common fixes I could find online. Those include:
Port forwarding
Creating a user with full read/write access to the entire dataset and running Plex under that user
Reinstalled Plex through both the HexOS deck and the TrueNAS interface
Enabled Host Network use
Ensured claim token is entered in the docker
Needless to say I am frustrated and out of possible solutions. Any help anyone could provide would be greatly appreciated.
