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!
