Error 404 with almost every docker container

Good morning there. Despite I'm new to Traefik I'm slowly learning how to use it.
I have a bunch of docker containers (each one defined by a docker-compose.yml file) on a home server reachable by IP address that I'd like to reverse proxy via Traefik V2.

My configuration is the following:

  • IP address: 192.168.1.23
  • Traefik version: v2.10.4
  • Host: Armbian (23.8.1) aarch64 on a Hardkernel ODROID-N2Plus
  • Docker version: 20.10.5+dfsg1, build 55c4c88

I'm currently having issues with speedtest-tracker container. Below its docker-compose.yml file

version: '3.3'
services:
    speedtest-tracker:
        container_name: speedtest-tracker
        environment:
            - PUID=1000
            - PGID=1000
            - DB_CONNECTION=mysql
            - DB_HOST=db
            - DB_PORT=3306
            - DB_DATABASE=speedtest_tracker
            - DB_USERNAME=XXXXXXXXXX
            - DB_PASSWORD=XXXXXXXXXX
            - TELEGRAM_BOT_TOKEN=XXXXXXXXXX
        volumes:
            - ./config:/config
        image: 'ghcr.io/alexjustesen/speedtest-tracker:latest'
        restart: always
        depends_on:
            - db
        networks:
          - web
          - internal
        labels:
          - traefik.enable=true
          - traefik.http.routers.speedtest-tracker.rule=Host(`192.168.1.23`)  && PathPrefix(`/speedtest-tracker`)
          - traefik.http.services.speedtest-tracker.loadbalancer.server.port=80
    db:
        image: mariadb:10
        restart: always
        environment:
            - MARIADB_DATABASE=speedtest_tracker
            - MARIADB_USER=XXXXXXXXXX
            - MARIADB_PASSWORD=XXXXXXXXXX
            - MARIADB_RANDOM_ROOT_PASSWORD=true
        volumes:
            - ./var_lib_mysql:/var/lib/mysql
        networks:
          - internal
        labels:
          - traefik.enable=false

networks:
  web:
    external: true
  internal:
    external: false

This is instead my Traefik configuration:

docker-compose.yml:

version: '3.3'

services:
  traefik:
    image: traefik:latest
    container_name: traefik
    volumes:
      - /var/run/docker.sock:/var/run/docker.sock
      - $PWD/traefik.toml:/traefik.toml
      - $PWD/traefik_dynamic.toml:/traefik_dynamic.toml
    ports:
      - "80:80"
    networks:
      - web

networks:
  web:
    external: true

traefik.yml:

[entryPoints]
  [entryPoints.web]
    address = ":80"

[api]
  dashboard = true

[providers.docker]
  watch = true
  network = "web"

[providers.file]
  filename = "traefik_dynamic.toml"

traefik_dynamic.toml:

[http.middlewares.simpleAuth.basicAuth]
  users = [
    "XXXXXXXXXXXXXXX" # Censored
  ]

[http.routers.api]
  rule = "Host(`192.168.1.23`)"
  entrypoints = ["web"]
  middlewares = ["simpleAuth"]
  service = "api@internal"

I can correctly start traefik container as well as speedtest-tracker but when I visit 192.168.1.23/speedtest-tracker the application replies with a generic HTTP 404 error.

Is there anything wrong with my configuration files?
Thanks in advance and sorry for the noobness, I'm a slow learner :stuck_out_tongue:

Are you sure the application itself is listening on path /speedtest-tracker? At least not according to the apps screenshots.
