Thank you very much for your help. That's very kind.

rclone config show freebox, post the command and output

type = ftp
host = ftp://mafreebox.freebox.fr/
user = freebox
pass = *** ENCRYPTED ***
port = 21
explicit_tls = true

techandapp@PAR-206287:~$

change
host = ftp://mafreebox.freebox.fr/
to
host = mafreebox.feeebox.fr

techandapp@PAR-206287:~$ rclone sync '/home/techandapp/torrents/Action 2019' freebox:/Freebox/Films

every time you change your config file you need to test it.
do rclone lsd freebox:

what's the solution to the problem

You have a typo in the name as it's supposed to be 'freebox' and you have'feeebox'
