title: Unable to Access HTTPs in AWS Application Load Balancer EC2 Instance
body: <p>I have an EC2 Instance, and want to add HTTPS to it. I am able to access it using http.</p>
  <p>I have added an Application Load Balancer, and enabled the Ports 80 and 443.</p>
  <p>I also added the DNS of the ALB in Route 53.</p>
  <pre><code>api.example.com alias to the ALB DNS
  </code></pre>
  <p>However, when I access the ALB using HTTP, it works fine. But when I try to do the same using HTTPs, it gives an error &quot;This site can’t be reached&quot;.</p>
  <p>Things I have already done:</p>
  <ul>
  <li>Added Certificate Manager to api.example.com</li>
  <li>Added HTTPs(Port 443) config to Security Groups.</li>
  </ul>
  <p>Can anyone help me out in this?</p>
