I have been pulling my h.a.i.r out for the last few hours trying to figure out what is going on and I think I've discovered something suspect.
When adding file sources and choosing the information provider (TMDB), it says it's version 4.0.1. I installed Kodi on my Android and it is showing version 5.0.3. My Nvidia Libreelec will not pull metadata where my Android will. The Nvidia box returns "Unable to Connect To Remote Server".
Updating the TMDB addon shows there are no updates available from 4.0.1.
I've reinstalled LE v8.2.1 and the new v8.2.2. Both show exactly the same thing.
