title: AWS EC2 certificate issue
body: <p>I was deploying my Spring Boot app using AWS EC2 and S3 by running a jar file on a virtual machine. However, I'm facing a security issue when trying to fetch this url from the browser, which listens to port <code>8443</code>: <code>https://ec2-3-20-235-15.us-east-2.compute.amazonaws.com:8443/</code></p>
  <p>However, I'm getting <a href="https://i.stack.imgur.com/fMFZS.png" rel="nofollow noreferrer"><img src="https://i.stack.imgur.com/fMFZS.png" alt="this error" /></a>, which say <code>NET::ERR_CERT_COMMON_NAME_INVALID</code>. I've been trying to look into how to get SSL certificates for my EC2 instance, but have not found a way yet. I would really appreciate any help on how to properly set this up. I'm completely new to AWS...</p>
  <p>Thank you.</p>
