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!

Try with the local network IP of the host PC/VM instead (192.168.x.x), you have to use that for most applications. Remember that localhost/127.0.0.1 means something different inside a Docker container than it does outside it…
Bingo! This worked. I don’t fully understand why because i expose the ports on the docker containers, i guess i must have something miss-configured. Thanks!!
If I understand correctly (and I’m not 100% sure I do), localhost in a Docker container lives in it’s own little network which is not the host’s network.
The container is its own localhost, which has its own ports (which is why you have to map an internal localhost port to a host PC localhost port for every container you wish to access). This means that Prowlarr in your case, has no idea what localhost:4666 should be since in Prowlarr’s localhost universe there exists nothing on that port. To access what the host knows of ports (instead of the container), you have to write the host’s address from inside the Prowlarr container.
I hope that wasn’t impossible to follow 😅
Now that I think about it (haven’t tried myself though) you could possibly add the mapping of port 4666:4666 to the Prowlarr Docker compose setup and then use localhost:4666 to access qBittorrent from inside Prowlarr.
I think you are right! Now that you’ve explained it, it makes sense in my head, as someone else recommended i added hostnames and now i can work with those which makes it nicer, i don´t want to be opening a maze of ports xd
Lol I hear ya 😅 But great that you got it to work for your setup. Best of luck with your projects!
