Other details

I've had this setup working for about a year now, never had issues.. I dont know what could have changed on my system for it to stop working... I've allowed spotdl.exe in my firewall a long time ago and doing it again didnt fix it. Should I do Uvicorn instead/also? Using the .exe for the WebUI (version 4.2.0) was able to fetch song and download it. Could it be that the client ID/secret of my config need to be changed/updated? Thanks for any help!

Hello, i just installed and got the same error, is there a solution?

i also got this error when i was changing some setting on casaos

Hi, I noticed the same error. I found in the "inspect/developer mode" that some calls were going to port 8800, instead of 8877. I am using the docker image, so instead of publishing the port 8877 to 8877, I published the port 8800 to 8877 and started working again.

Edit: When I run the docker image, I use the port 8877 "--port 8877".

[FaNt4zMa]

So I just updated and made a new config.. @cumal is definitly onto something because when using the default port 8800, I'm able to fetch and download songs from the WebUI, changing the port to anything else breaks it.. I don't know why that is the case, I've had it working on port 8098 for a very long time. Also, am I dumb or is there a way to run the WebUI in a docker container? Thanks

I'm also running into the red bubble with 'Error: "Network Error"' when I try to perform a search via the web UI of my spotdl instance, which is running as a docker container behind a reverse proxy. If I redirect the exposed reverse proxy port 8800 to the normal 443 https port, then it all works fine. So it seems like the problem may be that the HTTP header must specify a destination port of 8800.

Also, this problem seems to have been introduced as of v4.2.1 of the docker image (spotdl/spotify-downloader:v4.2.1), because I don't have this problem when reverting to v4.2.0.

Somewhere in here: https://github.com/spotDL/spotify-downloader/compare/v4.2.0...v4.2.1

EDIT: I've isolated the problem to this line: https://github.com/spotDL/spotify-downloader/blame/4f5d9b6e1f14a211cafaa936c66ad9b5d6a85e18/spotdl/console/web.py#L69

In v4.2.1, spotdl started using the master branch of spotdl/web-ui instead of the dev branch, and that's where the hard-coding of the port 8800 requirement appears to have been introduced. So I think the related web-ui bug that @snydergd identified above is the likely root of the problem.

@jspiers Oh thats great! I knew something had changed... Would you mind adding me on Discord and explain/show me how to run the WebUI on Docker? I've been trying to move all my self-hosted programs to a Docker Linux env instead of Windows but couldn't figure how to install SpotDL (and still have access to the WebUI..) Thanks :)

Edit: nevermind I figured it out, now I just need to know how to edit the config.json file.. On Windows it was easy to find, no idea where it is with the docker image :(

I've been trying to move all my self-hosted programs to a Docker Linux env instead of Windows but couldn't figure how to install SpotDL (and still have access to the WebUI..)

I do something similar myself, using docker compose for my self-hosted "homelab" setup to run spotdl behind a traefik v2 reverse proxy. My config might be a bit confusing with the multi-level file structure. I've seen other docker compose-based homelab setups that may be a bit cleaner.

[jspiers]

As a workaround for now, docker compose users can patch the docker image to use the dev branch of spotdl/web-ui (instead of master) by using an inline dockerfile which runs a sed regex replacement on the /spotdl/console/web.py file as follows:

services:
  spotdl:
    ...
    # comment out the docker image and use a build section instead
    # image: spotdl/spotify-downloader:v4.2.5
    build:
      dockerfile_inline: |
        FROM spotdl/spotify-downloader:v4.2.5
        RUN sed -i -e 's/web-ui\/tree\/master/web-ui\/tree\/dev/' /spotdl/console/web.py
   ...

Bring it up with docker compose up -d --build spotdl

Looking into this issue. Version 4.2.6 will have two new options --web-gui-location and --web-gui-repo

[xnetcat]

pushed an update to master, should be fixed :)
