Why ingress rules are not followed? default backend is reached instead

I finally figured out what I was missing. I added kubernetes.io/ingress.class: haproxy annotation and problem solved:

apiVersion: networking.k8s.io/v1beta1kind: Ingress  metadata:  name: ravendb  namespace: default  labels:    app: ravendb  annotations:    ingress.kubernetes.io/ssl-passthrough: "true"    kubernetes.io/ingress.class: haproxyspec:  rules:  - host: a.raven.aedas-prev.inercya.com    http:      paths:      - backend:          serviceName: ravendb-0          servicePort: 443        path: /  - host: tcp-a.raven.aedas-prev.inercya.com    http:      paths:      - backend:          serviceName: ravendb-0          servicePort: 38888        path: /  - host: b.raven.aedas-prev.inercya.com    http:      paths:      - backend:          serviceName: ravendb-1          servicePort: 443        path: /  - host: tcp-b.raven.aedas-prev.inercya.com    http:      paths:      - backend:          serviceName: ravendb-1          servicePort: 38888        path: /  - host: c.raven.aedas-prev.inercya.com    http:      paths:      - backend:          serviceName: ravendb-2          servicePort: 443        path: /  - host: tcp-c.raven.aedas-prev.inercya.com    http:      paths:      - backend:          serviceName: ravendb-2          servicePort: 38888        path: /

Now HAproxy ingress works as expected, reverse proxying external traffic to internal services.
