title: EC2 public instance not accessible
body: <p>I am facing this issue as I am new to AWS EC2. I have setup an instance and ssh working perfect. I installed httpd, mysql, php and httpd and mysql services running fine.</p>
  
  <p>I can't access EC2 public DNS in a browser. I already added a rule for HTTP with port 80 but still not working. What can be the other reasons? </p>
