title: ERR_SSL_PROTOCOL_ERROR when using AWS Load balancer
body: <p>I'm building Web app with AWS. I had a problem with AWS Load balancer.<br>
  I want every traffic transfer to <code>443</code> port, so I created Load balancer with a public certificate from ACM.<br>
  Site work ok when I have a certificate from Let'S encrypt in vhost, but when I remove Let's encrypt certificate, It got <code>ERR_SSL_PROTOCOL_ERROR</code>.<br>
  So I don't understand about ACM public certificate, and how can I fix this problem.  </p>
