I have been running Plex without problems for years but last week the drive containing Plex Medea Server died.
I installed a new drive, uninstalled Plex, installed Plex and added libraries.
The libraries updated, and downloaded metadata (movies and TV Programs) but not any artwork associated the the movie or TV program.
I see many have had this issue but I’ve not been able to find a solution.
I’ve tried:
Refreshing metadata for individual programs
Deleted all the cache files
The only errors showing in the Plex Media Server.log are
Sep 15, 2018 16:00:54.265 [6828] ERROR - CheckNetIsolation.exe exited with code 0x5
Sep 15, 2018 16:00:54.265 [6828] ERROR - Failed to grant application loopback exemption
at the start.
Server Version#: 1.13.5.5332
Player Version#: 3.57.1
