Traefik internal error pages

Traefik Traefik v3 (latest)
1

I have set up an error-pages middleware using the following compose file:

services:
   error-pages:
    image: ghcr.io/tarampampam/error-pages:3
    environment:
      TEMPLATE_NAME: noise
    networks:
      - traefik
    labels:
      traefik.enable: true
      traefik.http.routers.error-pages-router.rule: HostRegexp(`.+`)
      traefik.http.routers.error-pages-router.priority: 1
      traefik.http.routers.error-pages-router.entrypoints: web
      traefik.http.routers.error-pages-router.middlewares: error-pages-middleware
      traefik.http.middlewares.error-pages-middleware.errors.status: 400-599
      traefik.http.middlewares.error-pages-middleware.errors.service: error-pages-service
      traefik.http.middlewares.error-pages-middleware.errors.query: /{status}.html
      traefik.http.services.error-pages-service.loadbalancer.server.port: 8080

networks:
  public:
    external: true
  traefik:
    external: true

with the corresponding section in traefik.yml to automatically attach it to all traefik-managed containers:

entryPoints:
  web:
    address: :80
    http:
      middlewares:
        - error-pages-middleware@docker
  websecure:
    address: :443
    http:
      middlewares:
        - error-pages-middleware@docker

This works totally fine for all services running, except for the traefik service itself. If a container is down, traefik delivers a plain old 404 error page.

I can not for the life of me figure out, why this is the case and i could not find any information online that is about this specific scenario. I hope that there is someone here that could point me in the right direction.

Have you tried allowEmptyServices?

thank your for your input! although i was not aware of this setting, it sadly did not change the behavior.

traefik still delivers the plain old 404 page, when the service is down:

what i also noticed: the requests resulting in this plain old 404 do not even appear in the traefik logs smh.

I have never seen requests to Traefik not being logged. Except if you tell Traefik in config to not log certain status codes.
