AWS ALB with Traefik on Kubernetes - 404 error getting to app swagger page

Hello,

I am running the latest version of Traefik that's out, 2.4.8 that was installed via the helm chart. I have the traefik service setup as a NodePort type service so that I could use an AWS ALB. I am using the AWS ALB Ingress controller to provision the ALB. The reason I am using an ALB is because I have a requirement of stickying sessions and also need to support websockets connections from clients.

I am trying to access the swagger page like so:
https URL => AWS ALB => traefik inside k8s => app, but I am getting a 404 when doing so. I am seeing the traffic hit the traefik proxy, but with the 404..

Below is my ingress that points the ALB to my Traefik service

apiVersion: extensions/v1beta1
kind: Ingress
metadata:
  name: traefik-external-alb-ingress
  namespace: traefik-mesh
  annotations:
    alb.ingress.kubernetes.io/actions.ssl-redirect: '{"Type": "redirect", "RedirectConfig":
      { "Protocol": "HTTPS", "Port": "443", "StatusCode": "HTTP_301"}}'
    alb.ingress.kubernetes.io/backend-protocol: HTTP
    alb.ingress.kubernetes.io/certificate-arn: arn:aws:acm:us-east-1:xxxxxxx:certificate/xxxxxxxx
    alb.ingress.kubernetes.io/healthcheck-port: traffic-port
    alb.ingress.kubernetes.io/healthcheck-path: /ping
    alb.ingress.kubernetes.io/healthcheck-protocol: HTTP
    alb.ingress.kubernetes.io/listen-ports: '[{"HTTP": 80}, {"HTTPS":443}]'
    alb.ingress.kubernetes.io/scheme: internet-facing
    kubernetes.io/ingress.class: alb
  labels:
    app: traefik-external-alb
spec:
  rules:
    - http:
        paths:
          - path: "/*" 
            backend:
              serviceName: traefik-external-alb
              servicePort: 443

Below is my IngressRoute config:

---
apiVersion: traefik.containo.us/v1alpha1
kind: IngressRoute
metadata:
  annotations:
    kubernetes.io/ingress.class: traefik-external-alb
  name: signalhub-ingress-secure
  namespace: microservices
spec:
  tls: {}
  entryPoints:
    - websecure
  routes:
  - match: Host(`signalr-gateway-url.mydomain.com`)
    kind: Rule
    services:
    - name: signalr-api
      port: 8080
      sticky:
        cookie: {}
additionalArguments:
 - "--providers.kubernetescrd.ingressclass=traefik-external-alb"
 - "--ping.entryPoint=websecure"

I had to make some modifications on the ALB side for the health check to work, so in the values I have the health check port set to 8443 and ping is set to use the websecure entrypoint (for ping so the ALB can access it for the healthcheck). Any help or ideas would be greatly appreciated. Thanks!
