I'm having an issue with my PLEX server where it will not find movie posters for any new movies I have added in the last month. All I get is what appears to be a frame of the movie.
I have tried changing the Agent for Movies from The Movie Database to Freebase with no change. I have tried refreshing, and fixing incorrect match with no change. I also tried unmatching but I think this has broken one of them as it won't find the movie at all now. The movie titles and naming is correct as far as I can tell.
My Plex server is version 0.9.15.3 and is running on a QNAP TS-419P II firmware version 4.3.3.0262.
Any advice to get it working again would be appreciated.
