Really awesome script.
Was confused through the floor on why the hell I couldn’t log in. Turn out it’s a bug specific to 4.6.1, seemingly fixed in 4.6.2. That version killed the default password, but has a bugged generation of the new password: https://www.reddit.com/r/qBittorrent/comments/1827zqn/comment/kahat1u/?utm_source=share&utm_medium=web2x&context=3
Solution whitelist subnet login, login through a remote console, access localhost and change the password.
The generated password did appear in the logs, but only once and was not applied for whatever reason. Subsequent service restarts did not lead to new ones being generated.
