Can't add Slskd to Lidarr - Unexpected error: Connection refused (localhost:5030)

[Tonyloquent]

Hello,
Let me preface this by saying that I'm new to docker so there's a good chance I'm just doing something wrong, but at this point I've exhausted all the installation guides, forum posts, etc. to find a solution so here I am.
I currently have a Lidarr instance working with TrevTV's Tidal plugin. After exploring some other options to add I decided on adding Tubifarry for the soulseek support. Currently I'm stuck trying to add the Slskd indexer. I've verified that the API key that I made in the slskd instance lines up with the one being added for the Slskd indexer in Lidarr and that the web:, authentication:, api_keys:, my_apikeys:, key:, and role: are all uncommented in the slskd.yml file. Let me know if there is something I'm missing. I'd really love to get this working. Thank you.

It sounds like you've done a lot of the right steps already, so let’s focus on the likely issue: the host configuration. Since you're using Docker, the problem is almost certainly related to how localhost is being used. Here are multiple ways how to fix it:

---

Correct Host Configuration

1. Use the Container Name or Host IP:

   • If Lidarr and Slskd are running in separate Docker containers, localhost won’t work because it refers to the container itself, not the host or other containers.
   • Instead:
     • If both containers are on the same Docker network, use the container name as the host. For example, if your Slskd container is named slskd, use http://slskd:5030 in Lidarr's Slskd indexer settings.
     • If the port is exposed to the host (e.g., 5030:5030 in your Docker configuration), you can use the host machine's IP address. For example:
       • Find your host system's IP:
         • On Linux/macOS, run:

           hostname -I

         • On Windows, run:

           ipconfig

       • Use this IP in Lidarr's Slskd indexer settings, e.g., http://192.168.1.100:5030.

2. Verify Docker Network Setup:

   • Ensure both Lidarr and Slskd are on the same Docker network. You can check this with:

     docker network inspect <network_name>

   • If they’re not, create a shared network and connect the containers:

     docker network create shared_network
     docker network connect shared_network lidarr_container
     docker network connect shared_network slskd_container

3. Test Connectivity:

   • From the Lidarr container, test connectivity to Slskd:

     docker exec -it lidarr_container curl http://slskd:5030/api/v0/health

   • If using the host IP, test from the host machine:

     curl http://localhost:5030/api/v0/health

   • If this fails, the issue is likely network-related.

4. Double-Check Slskd Configuration:

   • Ensure your slskd.yml is correctly configured. For example:

     web:
       host: 0.0.0.0 # Allow external access
       port: 5030
     
     authentication:
       api_keys:
         my_apikeys:
           - key: YOUR_API_KEY_HERE

   • Make sure there are no trailing spaces in the API key.

By using the container name or host IP (if the port is exposed), you should be able to resolve the connectivity issue. Let me know if you need further help! 🐳

Simply putting my hosts ip followed by the port worked. I went ahead and put the docker containers on the same network since I didn't have that set up either and just changed the URL to http://slskd:5030/ in lidarr like you said. The request seem to be working in slskd now, but now whenever Lidarr tries to move the files from soulseek downloads folder to my main library it keeps giving me an error "Failed to import track, Permissions error"

I think I might be boned here. I could be wrong but I was checking the configuration page on the slskd github and it looks like I can't change the permissions of files generated with docker desktop. I've tried all the advice you gave in that other discussion post, but nothing seemed to fix my problem.

No matter what I do this is the outcome every time.

Crossing my fingers that there is something else I can do to fix this other than having to change my OS.

The umask settings allow you to configure default read/write permissions for new files and directories. You have the option to set it to 000 for maximum permissions. Additionally, as indicated in your screenshot, you can configure both slskd and Lidarr to run under the same user account to ensure consistent file access permissions between these applications.

Just wanted to say thank you for your help. I finally got everything working properly!
