title: Set up an instance on AWS-Amazon but cannot connect
body: <p>I am fairly new at EC2 technology so I think I am missing some points. So I set up an instance which is running and had created two key pairs. I choose the instance, choose "Connect" and the site gives me instructions about that. I follow them and when I execute the ssh command returns that "network is unreachable". Can you help me please?  </p>
