Kubernetes Cluster | Unable to launch the application using Master Node


Cluster information:

Kubernetes version: v1.14
Cloud being used: (put bare-metal if not on a public cloud) Microsoft Azure
Installation method: kubeadm
Host OS: Linux-Ubuntu
CNI and version: Calico
CRI and version: Docker

Problem Statement:

I have two Virtual Machines (Linux-Ubuntu) on Microsoft Azure one as a master node and other as a worker node. In my kubernetes cluster I have deployed a Nginx server which has been assigned to worker Node.

The problem is I am able to access the Nginx server on worker node ip i.e using command: curl ip_address_of_Nginx_pod but when I try to run the same command on Master Node its not working.

There is some issue with Inbound Rules I think. However I have already allowed all traffic on both master and worker node.

On Master Node:

Once I run Command : kubectl get pods

NAME         READY   STATUS    RESTARTS   AGE   IP            NODE              
myfirstpod   1/1     Running   1          23h   demo-my-worker 

Once I run Command : curl , It does not display anything…

root@Demo-my-master:~/demo# curl

On Worker Node:

Once I run Command : curl, it runs perfectly fine.

root@Demo-my-worker:~/demo# curl
