I have received this message a few times now and also after the most recent update so I am submitting. I am currently using build time 2019-04-20 00:25, and this exact issue was on the build prior. It appears to be mostly centered on TMDB. I was able to scrap IMDB ok, but images TMDB and Trakt do not work.
