FileBot will cache external data with extreme prejudice. Which is generally not a problem, but if you absolutely need to fetch the latest data from the server then you can just clear the cache and try again.
Press
CTRL+SHIFT+DEL (clear active caches only)
Run
filebot -clear-cache (clear all caches)
DO NOT clear the cache unless you have a good reason for doing so.
ONLY users that actively contribute to TheTVDB or TheMovieDB may clear the cache.
DO NOT clear the cache preemptively each and every time
filebot is called.
ONLY ever clear the cache manually if and when you have good reason for doing so, e.g. for testing and debugging.

Please read
License Error: Banned due to abuse if you plan on using
-clear-cache before each and every
filebot call in unattended scripts and automation.
