title: Why is my auto scaling EC2 instance reported as 'out of service' by the load balancer?
body: <p>I'm having an issue with an Amazon EC2 instance during auto scaling. Every command I typed worked. I found no errors. But when testing whether auto scaling is working or not I found that it works until the instance started. The newly spawned instance does not work afterwards though: It's under my load balancer but its status is out of service. One more issue is when I copy and paste the public DNS link into the browser it does not respond and an error is triggered like "firefox can't find ..."</p>
  
  <p>I doubt that there should be problem with the image or the Linux configuration.</p>
  
  <p>Thanks in advance.</p>
