Traefik reverse proxy with Joal – WebSocket not working (404 error)

[maxhugit]

Hi everyone, I’m trying to run Joal behind Traefik on Unraid but I can’t get WebSocket to work. I’d appreciate any help or advice.

Problem

I’m trying to run Joal behind Traefik on Unraid, but I can’t get the websocket to work properly.

Setup

Joal is installed with the following command:

docker run
  -d
  --name='joal'
  --net='container:GluetunVPN'
  --pids-limit 2048
  -e TZ="Europe/Paris"
  -e HOST_OS="Unraid"
  -e HOST_HOSTNAME="Unraid"
  -e HOST_CONTAINERNAME="joal"
  -e 'TZ'='Europe/Brussels'
  -e 'JOAL_SECRET_OBFUSCATION_PATH'='joaleeS8efie'
  -e 'JOAL_SECRET_TOKEN'='eikoogei8yohphaph6eiza3EraaChav2jee8lood9iegaing'
  -e 'JOAL_PORT'='3965'
  -e 'AUTOUPGRADE'='0'
  -e 'UID'='99'
  -e 'GID'='100'
  -l net.unraid.docker.managed=dockerman
  -l net.unraid.docker.webui='http://192.168.100.218:[PORT:3965]/joaleeS8efie/ui/'
  -l net.unraid.docker.icon='https://raw.githubusercontent.com/anthonyraymond/joal-desktop/master/resources/icons/1024x1024.png'
  -v '/mnt/user/appdata/joal':'/config':'rw'
  --restart unless-stopped 'digrouz/joal'

Traefik configuration:

http:
  routers:
    joal-redir:
      rule: "Host(`joal.mydomain.fr`)"
      entrypoints:
        - web
      middlewares:
        - redirect-to-https@file
      service: joal-service
    joal-router:
      rule: "Host(`joal.mydomain.fr`)"
      entrypoints:
        - websecure
      middlewares:
        - gzip-compress@file
      service: joal-service
      tls: {}
  services:
    joal-service:
      loadBalancer:
        servers:
          - url: "http://192.168.100.218:3965"

Error

When I connect to https://joal.mydomain.fr, I get this in the browser console:

URL: wss://joal.mydomain.fr:80/
Status: 404 Not Found

Tried
• Different Traefik rules (with PathPrefix, middlewares, etc.)
• Changing the container port mapping
• Adjusting TLS / entrypoints

Question

Has anyone successfully configured Joal with Traefik including websocket support?
Do I need to set --joal.ui.proxy.websocket.path and --joal.ui.proxy.host explicitly, or is there a simpler Traefik config I’m missing?
