Welcome!

  • Yes, I've searched similar issues on GitHub and didn't find any.
  • Yes, I've searched similar issues on the Traefik community forum and didn't find any.

What did you do?

expecting error middleware to give response code of the error page invocation, instead is always giving the http code error that i am handling in middleware.

ingressroute
  routes:
  - kind: Rule
    match: Host(`traefik-demo-east.corp`) && PathPrefix(`/`)
    middlewares:
    - name: failover-onerror
    services:
    - kind: Service
      name: nginx
      nativeLB: true
      port: 80

middleware:
  errors:
    query: /
    service:
      name: nginx
      namespace: traefik-demo-failover
      port: 80
      scheme: http
    status:
    - 500-599

What did you see instead?

In this example my curl output always giving 502 followed error url response content.
I am expecting client should not be served with 502 response as i am handling to redirect to different service to fulfill the same request.

$ curl -i http://traefik-demo-east.corp
