Traefik v2 router selection issues

Traefik Traefik v2
1

Hey everyone,

Has anybody ran into this issue where no router seems to be selected and trafik keeps returning 404s?

What did you do?

Setup traefik with the following configs:

entryPoints:
  web:
    address: ":80"
  web-secure:
    address: ":443"

log:
  level: DEBUG

accessLog: {}

api:
  dashboard: true
  insecure: true

certificatesResolvers:
  le:
    acme:
      email: admin@everflow.io
      storage: acme.json
      tlsChallenge: {}


providers:
  file:
    filename: /etc/traefik/config.yml

http:
  routers:
    tracking:
      entryPoints:
        - web
        - web-secure
      rule: "Host(`tracking.olivierboucher.com`)"
      service: tracking@file
      priority: 1
      tls:
        certResolver: le
        domains:
          - main: "tracking.olivierboucher.com"
  services:
    tracking:
      loadBalancer:
        passHostHeader: true
        servers:
        - url: "http://130.211.40.247"

What did you expect to see?

Be served the content available on http://130.211.40.247

What did you see instead?

A 404 error

It seems like traefik is unable to select a proper router. I also tried different rules (like a match all regex or / path prefix) but all of them still continued to give the 404.

Hey :slight_smile:

That's actually a false "assumption" lets say. You have set the service tracking to use the url http://130.211.40.247 as a backend.

You should see the page, once you try to hit tracking.olivierboucher.com as this is the rule on your router :slight_smile:

Sorry if that was not clear but that's what I am doing... This config is live at the moment, you can hit tracking.olivierboucher.com and see the 404

Hello,

sorry, I was on vacation :slight_smile: It currently works as intended. You did select the router to be a TLS Router which resolves certificiates over Lets Encrypt.

Thus, with that configuration, you need to hit your page with https://tracking.olivierboucher.com .

If you want to have automatic redirection, you will need to create a seperate router which does the job.
