Hi all, i’m having issues configuring prowlarr to use the qbit torrent downloader. I have everything setup in a docker container as such:

I can open localhost:4666 in firefox and see the qbit web interface. When i go to the prowlarr interface and try to connect to it the field for the adress goes red and says: unable eto connect tot qBittorrent. The logs say:

I’ve tried looking for help online but i haven’t found much so some help would be appreciated.

Thank you!

    I recommend adding hostname: app-name lines for each container then you can just use the hostname and the native port (even if you don’t pass it through with a port: line).

    It’s super useful if you want to expose any apps with a reverse proxy like Caddy. That way the ONLY way to access an apps web interface is via the reverse proxy. Then look at filter rules to deny access unless the client has a LAN IP.

    Poof, you’ve got SSL and custom subdomains for all your apps, but still only on your LAN or personal VPN (like Wireguard or Tailscale).

      Thats good!! i’m now looking at how to set up caddy to do exactly just just that, then i’ll look at the vpns for outside connections. Thanks gor the advice!

        When you figure out how to set up Caddy, please send me a PM… I’ve tried and given up, but probably managed to misconfigure or misunderstand something.

        For outside access I use Ngrok so I don’t have to bother with router settings. Probably isn’t recommended, but it was easy to set up and has worked flawlessly for me for years.

          I got it to run, its fairly simple but i am having issues integrating it into the docker compose as it just… stops working… i’ll be looking into it today and tomorrow and if i succeed i’ll report back to you with findings.

          If you want to PM me your docker-compose.yml and Caddyfile I’m more than happy to take a look at them for you. I’ve been using Caddy as my rev-proxy for 10+ app stacks for a few years now.
