title: Client sent an HTTP request to an HTTPS server - Kubernetes cluster
body: <p>I have created a Kubernetes cluster in the <a href="https://upcloud.com/community/tutorials/deploy-kubernetes-using-kubespray/" rel="nofollow noreferrer">cloud- using this tutorial</a> and deployed [to the cluster] a backend application called <code>chatapp</code> from the Docker private registry. Since there is no option to include service type as <code>LoadBalancer</code>, I had to restore to <code>NodePort</code> type.
  Here is the <code>chatapp-deployment.yml</code> file for reference:</p>
  <pre><code>apiVersion: v1
  kind: Service
  metadata:
    name: chatapp
  spec:
    selector:
      app: chatapp
    ports:
    - protocol: &quot;TCP&quot;
      port: 6443
      targetPort: 3000
    type: NodePort
    externalIPs:
    - A.B.C.D
  
  ---
  apiVersion: apps/v1
  kind: Deployment
  metadata:
    name: chatapp
    labels:
      app: chatapp
  spec:
    replicas: 2
    selector:
      matchLabels:
        app: chatapp
    template:
      metadata:
        labels:
          app: chatapp
      spec:
        imagePullSecrets:
        - name: regsecret
        containers:
        - name: chatapp
          image: sebastian/chatapp
          imagePullPolicy: Always
          command: [&quot;/bin/sh&quot;]
          args: [&quot;-c&quot;, &quot;while true; do echo hello; sleep 10;done&quot;]
          ports:
            - containerPort: 3000
  </code></pre>
  <p><strong>Note:</strong> I removed the external IP for security reasons.</p>
  <p>I had to assign external IP manually since I couldn't set-up <code>LoadBalancer</code> as service type. Whenever I try accessing <code>http://A.B.C.D:6443</code>, I get the following:</p>
  <pre><code>Client sent an HTTP request to an HTTPS server.
  </code></pre>
  <p>I went through this <a href="https://stackoverflow.com/questions/61017106/client-sent-an-http-request-to-an-https-server">link</a> but couldn't fix my issue with it. The external IP I have used is from the <code>master-o</code>.</p>
  <p>While trying to access it with <a href="https://A.B.C.D:6443" rel="nofollow noreferrer">https://A.B.C.D:6443</a>, I get the following <code>403</code> message:</p>
  <pre><code>{
    &quot;kind&quot;: &quot;Status&quot;,
    &quot;apiVersion&quot;: &quot;v1&quot;,
    &quot;metadata&quot;: {
      
    },
    &quot;status&quot;: &quot;Failure&quot;,
    &quot;message&quot;: &quot;forbidden: User \&quot;system:anonymous\&quot; cannot get path \&quot;/\&quot;&quot;,
    &quot;reason&quot;: &quot;Forbidden&quot;,
    &quot;details&quot;: {
      
    },
    &quot;code&quot;: 403
  </code></pre>
  <p>How can I authorize access to my cluster? Any feedbacks and suggestions would be appreciated.</p>
