It is important to know that the movie grabber 'tmdb3.py'
limits each action to 30 seconds.
But MythTV internally limits a grabber session to 60 secs.
Additionally, the tmdb3 grabber uses an internal cache.
The cache is located at ' $HOME/.mythtv/cache/pytmdb3.cache'
or defined by the 'MYTHCONFDIR' environment.
That might explain your observation, that the second call
from the terminal succeeds, if the calls are done by the
same user on the same PC.

Please try the following steps:
- delete the cache
- from mythfrontend, run a single update/fetch command
  that failed previously
- delete the cache again
- run the tmdb3 command logged by mythmetadatalookup
  from the terminal again (as the same user)
- post the output

If that fails as well, try to increase the timeout for tmdb3
to 60 seconds. See
https://forum.mythtv.org/viewtopic.php?f=36&t=3630
how to change the timeout.

On the other hand, it is of interest, if the second call
from the terminal returns *all* the content, or if it
returns the truncated content from the cache, only.

An example for a failed command would be helpful.
