Why do I have different behavior between nova2.py and qBittorrent search

[Rayutto]

Hello all,
I am using qBittorrent-nox v4.2.5 and python 3.9.2 and trying to do some torrent search (using jackett) and I have a weird behavior.
First I don't think I have an issue with my jackett install because when I call nova2.py with jackett everything is fine and I get an answer with the good torrent.

However, calling the same script with qBittorrent (doing a search in the UI) gives me an error. I have tracked the error to a jackett function (called get_response, responsible for HTML requests).

What I don't understand is that the jackett.py function seems to be called exactly the same way (same python working directory, same python version, same external library version, etc...) but I get an error doing a HTML request with jackett when I use qBittorrent and no error when I call the same code with nova2.py.

Am I missing something ? Do not hesitate if you have questions.

Many thanks,
