@ChuckPa I’m using TMDB and TheTVDB as well.
I removed my patch on 11/24 after I got the artwork to pull for my TV shows and movies.
I just tried to reproduce the problem today, but the last time I saw the error in the logs was yesterday, 11/25.

The file com.plexapp.agents.thetvdb.log.1 starting on line 247 was the last time I saw this pop up.
My best guess is that the problem wasn’t with PMS or TMDB / TheTVDB, but instead with CloudFlare and the way they modified the response headers.
There was a carriage return, but no newline character, so the regex to validate the header failed and the Python library considered it a bad response. I just appended a \n to the header when the regex failed and that worked as a stop gap.
