title: Can´t connect to my Amazon EC2 instance. It pings but connection times out
body: <p>I did setup my 1st EC2 instance on AWS on a free tier using Ubuntu as the OS. I followed all the steps and my instance is up.</p>
  
  <p>I´ve build the following security rules:</p>
  
  <pre><code>Ports   Protocol    Source  Personal_SG_NVirginia
  80      tcp         0.0.0.0/0   ✔
  22      tcp         0.0.0.0/0   ✔
  3306    tcp         0.0.0.0/0   ✔
  443     tcp         0.0.0.0/0   ✔
  -1      icmp        0.0.0.0/0   ✔
  </code></pre>
  
  <p>I can ping my instance, but cannot connect to it either using PuTTY, ssh on my linux and even on miniterm console.</p>
  
  <pre><code>$ ssh -vv -i "xxxx.pem" ubuntu@52.91.95.205
  OpenSSH_6.6.1, OpenSSL 1.0.1f 6 Jan 2014
  debug1: Reading configuration data /etc/ssh/ssh_config

  ssh: connect to host 52.91.95.205 port 22: Connection timed out
  </code></pre>
  
  <p>Tha same happens if I use DNS name.</p>
  
  <p>Miniterm console error:</p>
  
  <pre><code>Connection to 52.91.95.205: Connection timed out: no further information
  </code></pre>
  
  <p>I have already restarted the instance and recreated it, but no success at all.</p>
