Unable to get kubernetes dashboard

Question

I've installad a new cluster (version 1.13.5 of kubectl kubelet kubeadm), then I've installed flannel and add a worker node. Now I'm trying to add kubernetes dashboard to my cluster but after i run

$ kubectl apply -f https://raw.githubusercontent.com/kubernetes/dashboard/v1.10.1/src/deploy/recommended/kubernetes-dashboard.yaml

I've this situation

kubernetes-dashboard-****   0/1     CrashLoopBackOff   1          8s

Then if I get the log i can see this

 Error while initializing connection to Kubernetes apiserver...

Where I'm wrong?

can you curl to you api server? `curl -v $(kubectl describe pod kube-apiserver-master -n kube-system | grep IP:|awk '{print $2}'):6443` — A_Suh, Apr 15 '19 at 10:35

It seems that the problem was on the worker, when I put the dashboard on master the pod starts. Maybe the kube dashboard has to be installed on the master or there is something wrong with flannel and the master-node communication.

Check api-server pod is running or not and KubeDNS is working fine or not.
