Credentials

Username: admin
Password: stored in Vaultwarden as QBITTORRENT_ADMIN

On first start, container logs print a temporary admin password. Replaced on initial setup; permanent password lives in Vaultwarden.

Reverse proxy / host header

qBittorrent rejects requests when the Host header doesn't match localhost. To work behind Caddy, the following preferences are set (already applied):

web_ui_host_header_validation_enabled: false
web_ui_reverse_proxy_enabled: true
web_ui_reverse_proxies_list: 127.0.0.1/32,172.16.0.0/12

Caddy entry:

tor.alogins.net {
    reverse_proxy localhost:8085
}

Storage Note

Downloads currently land in /mnt/misc/qbittorrent/downloads. /mnt/misc is a temporary location — move to a dedicated media volume when capacity planning is settled.
