Difficulties to route traffic to external host

Hi,

I started using Traefik just today, after watching many hours of keynotes and everything related to Traefik, I have to admit it's a huge tech change from my old nginx reverse proxy !

I've successfully set up every subdomain redirect for every docker container I wanted to, but I'm struggling on making it work for external services, such as DSM (Synology Dashboard), running on my NAS.

docker-compose.yaml

services:
  traefik:
    image: traefik:latest
    container_name: traefik
    restart: unless-stopped
    ports:
      - 80:80
      - 443:443
      - 38080:8080
    volumes:
      - /var/run/docker.sock:/var/run/docker.sock:ro
      - ./DATA/traefik/letsencrypt:/letsencrypt
      - ./DATA/traefik/traefik.toml:/traefik.toml
      - ./DATA/traefik/conf.d/rules.toml:/etc/traefik/conf.d/rules.toml
    networks:
      - web
      - internal

traefik.toml

[global]
  sendAnonymousUsage = false

[log]
  level = "DEBUG"

[providers]
  [providers.docker]
    endpoint = "unix:///var/run/docker.sock"
    watch = true
    exposedByDefault = true
    swarmMode = false
  [providers.file]
    filename="/etc/traefik/conf.d/rules.toml"
    watch=true

[api]
  dashboard = true
  debug = false
  insecure = true

[entryPoints]
  [entryPoints.insecure]
    address = ":80"
  [entryPoints.secure]
    address = ":443"

[certificatesResolvers.myresolver.acme]
  email="me@example.conf"
  storage="/letsencrypt/acme.json"
  [certificatesResolvers.myresolver.acme.dnschallenge]
  provider="ovh"

rules.toml

 [http]
  [http.middlewares]
    [http.middlewares.nas-redirect.redirectScheme]
        scheme = "https"

  [http.routers.nas-redirect]
    entrypoints = ["insecure"]
    rule = "Host(`dsm.domain.net`)"
    middlewares = ["nas-redirect"]
    service = "service_nas"

  [http.routers.service_nas]
    entrypoints = ["secure"]
    rule = "Host(`dsm.domain.net`)"
    service = "service_nas"
    [http.routers.service_nas.tls]
        certResolver = "myresolver"

  [http.services]
    [http.services.service_nas.loadbalancer]
      [[http.services.service_nas.loadBalancer.servers]]
        url = "http://192.168.1.22:5000"

Each request to dsm.domain.net gives me a warning on Chrome, with the Traefik default cert, and logs states that dsm.domain.net isn't recognized, serving default certificate.

I tried to follow everything, but I must be missing something obvious to you guys.

Thanks in advance for the provided help :slightly_smiling_face:

Cheers !

I got my answer, didn't know that Traefik was THAT case sensitive.

    [http.services.service_nas.loadbalancer]
      [[http.services.service_nas.loadBalancer.servers]]
        url = "http://192.168.1.22:5000"

Missed that capital B in the first loadbalancer declaration, now everythings works okay...
