Unable to get the metrics from heapster pod in Kubernetes Cluster - kubernetes

Question

I am trying to get the metrics in Kubernetes dashboard. For that I'm running the influxdb and heapster pod in my kube-system namespace. I checked the status of pods using the command kubectl get pods -n kube-system. Here is the link which I was followed But heapster shows the logs as
E1023 13:41:07.915723 1 reflector.go:190] k8s.io/heapster/metrics/util/util.go:30: Failed to list *v1.Node: Get https://kubernetes.default/api/v1/nodes?resourceVersion=0: dial tcp: i/o timeout
Could anybody suggest where might be I will do the changes in my configurations?

Looks like the heapster cannot talk to you kube-apiserver through the kubernetes service on your default namespace. A few of things, you can try:
Check that the service is defined in the default namespace:
$ kubectl get svc kubernetes
NAME TYPE CLUSTER-IP EXTERNAL-IP PORT(S) AGE
kubernetes ClusterIP 10.96.0.1 <none> 443/TCP 92d
Check that all your kube-proxy pods are running ok:
$ kubectl -n kube-system -l=k8s-app=kube-proxy get pods
NAME READY STATUS RESTARTS AGE
kube-proxy-xxxxx 1/1 Running 0 4d18h
...
Check that all your overlay pods are running. For example for calico
$ kubectl -n kube-system -l=k8s-app=calico-node get pods
NAME READY STATUS RESTARTS AGE
calico-node-88fgd 2/2 Running 3 4d21h
...
