Thank you.
So here we have CR LF as end of line in the cookies lines
com.plexapp.system
com.plexapp.agents.thetvdb
These appear to expire in March and April 2020
My theory is that these came over from a windows install where end of line is CR LF whereas on Linux it is LF. They have long expiry and a recent change to one of the http modules introduced some extra validation tripping over the unexpected carriage return
It should be sufficient to delete these HTTPCookies files and they will get recreated
I would be interested if we do still end up with a CR LF at the end of line after doing this
So just delete
Application Support/Plex Media Server/Plug-in Support/Data/com.plexapp.agents.thetvdb/HTTPCookies
and
Application Support/Plex Media Server/Plug-in Support/Data/com.plexapp.system/HTTPCookies
and refresh all metadata for the libraries
If still an issue, would like logs and the zipped HTTPCookies files
