Losing that GUI login is annoying, but nothing's actually broken. Editing the config file by hand is what left you stuck (deleting that line doesn't reset it to the default, it just removes the check). There's a built-in command that does this cleanly: over SSH, run sudo sparkbox reset-password qbit — it stops qBittorrent, writes a fresh password straight into its own config, then starts it back up, so there's no drift between what's saved and what qBit actually has. The new password gets written to /opt/sparkbox/state/qbittorrent-admin-password.txt (username stays admin). If Radarr/Sonarr are hooked into qBit, update the password there too once you're back in.
