I stopped the plexmediaserver, then went into /usr/local/plexdata/ and based on another user’s suggestion in the server-windows topics ( https://forums.plex.tv/t/no-metadata-from-tvdb-and-moviedb/440755/35?u=supercazzola ) emptied caches in /Plex Media Server/Plug-in Support/Caches/ ( rm -rf on both com.plexapp.agents.thetvdb and com.plexapp.agents.themoviedb ) and for the most part, I am no longer seeing this issue after restarting the plexmedia server.
