Multiple "/dashboard" redirects when using haproxy

So I have a weird setup. We are using haproxy as a LB for several Traefik v2 ingress containers within K8s. And I am trying to route the dashboard through an Ingress object. And it is adding /dashbaord continuously to the url.

Current Args from the deployment :

#        - "--api=true"
        - "--api.insecure=true"
        - "--providers.kubernetesingress"
        - "--entrypoints.web.address=:80"
        - "--metrics.prometheus=true"
        - "--metrics.prometheus.addEntryPointsLabels=true"
        - "--metrics.prometheus.addServicesLabels=true"
        - "--accesslog=true"
        - "--global.sendAnonymousUsage=false"

And the ingress object :

apiVersion: extensions/v1beta1
kind: Ingress
  name: traefik-ingress
  namespace: ingress-traefik
  annotations: traefik PathPrefix
    - host:
        - path: /api || /dashboard
            serviceName: traefik-ingress-service
            servicePort: 8080

here is the haproxy log : [20/Dec/2019:05:13:17.955] traefik traefik/server1 0/0/1/2/3 404 180 - - ---- 1/1/0/0/0 0/0 "GET /dashboard/dashboard/dashboard/dashboard/dashboard/dashboard/dashboard/dashboard/dashboard/dashboard/dashboard/dashboard/dashboard/dashboard/dashboard/dashboard/dashboard/dashboard/dashboard/dashboard/ HTTP/1.1"

haproxy.cfg :

       server server1 check

The docs say to use the insecure api. Not sure what I am missing. Has anyone been able to make this work? I want to disable port 8080...

Idez, that works great with Docker Swarm. I run that on another cluster. I am asking about Kubernetes. Does anyone have a kube yaml that shows how to set this up?

something like that:

kind: IngressRoute
  name: traefik-web-ui
  namespace: yournamespace
    - web
  - match: PathPrefix(`/api`) || PathPrefix(`/dashboard`)
    kind: Rule
    - name: api@internal
      kind: TraefikService

I have everything set up exactly like this in my kubernetes cluster. The problem is the dashboard is accessible from inside the cluster, even kubernetes nodes, but I can not access it from outside(internet).
my request is getting into the cluster but is lost inside, it seems NAT is doing some strange magic on machines
Anybody met this kind of behavior?
Thanks in advance

One more strange thing, I am able to access for example, but dashboard is not working

I am not using api.insecure, I am using api@internal TraefikService as defined in documentation

Thanks for the response

Still trying to find a way to make this work without a CRD. Here is the exact yaml I am using
