I have a kubernetes cluster in IBM cloud which has a daemonset and backend pods. I had setup a network policy where backend service can accept daemonset requests. But the daemonset shows Connection Refused error when sending requests to backend pods. Any idea?

Daemonset yaml

apiVersion: extensions/v1beta1
kind: NetworkPolicy
metadata:
  name: ds-network-policy
spec:
  podSelector:
    matchLabels:
      component: ds
  policyTypes:
  - Ingress

Backend yaml

apiVersion: extensions/v1beta1
kind: NetworkPolicy
metadata:
  name: backend-network-policy
spec:
  ingress:
  - from:
    - podSelector:
        matchLabels:
          component: ds
  podSelector:
    matchLabels:
      component: backend
  policyTypes:
  - Ingress
