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

version: "3.2"
services:
  qbittorrent:

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...

[–] salieri@lemmy.world 3 points 1 year ago (1 children)

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!!

[–] sarjalim@lemm.ee 5 points 1 year ago* (last edited 1 year ago) (1 children)

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.

[–] salieri@lemmy.world 1 points 1 year ago (1 children)

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

[–] sarjalim@lemm.ee 2 points 1 year ago

Lol I hear ya 😅 But great that you got it to work for your setup. Best of luck with your projects!

[–] cory_lowry@lemmy.world 2 points 1 year ago (1 children)

Try using the ip_address:4666

[–] salieri@lemmy.world 1 points 1 year ago (2 children)

i tried with 127.0.0.1:4666 but i got the same issue

[–] cory_lowry@lemmy.world 1 points 1 year ago (1 children)

What IP is the machine?

[–] cory_lowry@lemmy.world 1 points 1 year ago

I use 192.168.x.x:port_number to access it

[–] novarime@sopuli.xyz 2 points 1 year ago* (last edited 1 year ago) (1 children)

I've previously had issues with timezones, and yours are all over the shop.

[–] salieri@lemmy.world 1 points 1 year ago

yeah, that and other stuff its very hacky. I've now done a .env file to keep everything parametrized.

[–] salieri@lemmy.world 2 points 1 year ago* (last edited 1 year ago)

Version information:

qBit: v4.5.4
prowlarr: 1.7.4.3769
[–] Qantumentangled@lemmy.farley.pro 2 points 1 year ago (1 children)

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).

[–] salieri@lemmy.world 1 points 1 year ago (1 children)

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!

[–] sarjalim@lemm.ee 1 points 1 year ago (2 children)

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.

[–] salieri@lemmy.world 1 points 1 year ago

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.

[–] Qantumentangled@lemmy.farley.pro 1 points 1 year ago

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.

[–] zerodawn@leaf.dance 1 points 1 year ago (2 children)

What's the use case to adding qbittorrent to prowlarr?

[–] rambos@lemm.ee 2 points 1 year ago

Usecase is adding indexers to prowlarr and then prowlarr can grab a torrent/usenet and add it to qbittorrent. But real benefit is having sonarr/radarr look for new shows/movies the way you told them and grab torrents -> rename -> place in library -> enjoy amazing jellyfin/plex. Holly automation of home media, amazing experience. Just look at OPs compose file, its all you need. I would just consider one more container, gluetun to hide everything behind VPN (if you are paying for one)

[–] salieri@lemmy.world 2 points 1 year ago

I was just starting to fiddle with the Starr programs so i didn't realize that the proper way to use it is to sync the torrent clients directly to sonarr and radarr. The issue happened on those programs all the same though. (fixed it already though)

[–] AbidanYre@lemmy.world 1 points 1 year ago* (last edited 1 year ago)

I think I ended up putting localhost in the *rr web page to connect to qbittorrent.

Acronyms, initialisms, abbreviations, contractions, and other phrases which expand to something larger, that I've seen in this thread:

Fewer Letters More Letters
IP Internet Protocol
SSL Secure Sockets Layer, for transparent encryption
VPN Virtual Private Network

3 acronyms in this thread; the most compressed thread commented on today has 13 acronyms.
