title: Traefik & Keycloak: error SSL_ERROR_RX_RECORD_TOO_LONG
body: <p>I use an <code>HAProxy</code> to redirect all requests from 80 port to a 443 and using a NodePort to enter on a <code>traefik-ingress-controller</code> (v1.6.6, inside a Kubernetes cluster).</p>
  
  <p>Here the <code>HAProxy.conf</code>:</p>

  <p>Every application running on my Kubernetes cluster has an Ingress.</p>
  
  <p>Among them I have a Keycloak pod (v4.1.0, for the authentication) with this ingress:</p>
  
  <pre><code>apiVersion: extensions/v1beta1
  kind: Ingress
  metadata:
    name: keycloak
    annotations:
      kubernetes.io/ingress.class: traefik
  spec:
    rules:
    - host: login.myapp.it
      http:
        paths:
        - backend:
            serviceName: keycloak
            servicePort: 8080

  <p>When I connect to <a href="https://login.myapp.it/auth/admin/" rel="nofollow noreferrer">https://login.myapp.it/auth/admin/</a> I get redirected to
  <a href="https://login.myapp.it:80/auth/admin/master/console/" rel="nofollow noreferrer">https://login.myapp.it:80/auth/admin/master/console/</a> (note the port 80) and I received an <code>SSL_ERROR_RX_RECORD_TOO_LONG</code> error.</p>
  
  <p>Someone has some hints for this redirect issue with keycloak behind proxy?</p>
  
  <p>Thank you in advance.</p>
