title: AWS EC2 keep refusing my private SSH 2 key
body: <p>Already looked for a solution but nothing seems to be helpfull, I'm doing everything that is meant to be made and my instance keeps returning me the message "Server refused our key".</p>
  
  <p>Here's what I've been doing:</p>
  
  <pre><code>1) Create Instance;
  2) Download the .pem key;
  3) PuttyGen to transform it in a private .ppk (SSH-2 RSA);
  4) Associate an Elastic IP to the Instance;
  5) Connect through 22 with the correct auth key generated on the 3rd step;
  6) Server asks for username, insert "ubuntu" (using 12.04.1 LTS);
  7) Server returns "Server refused our key".
  </code></pre>
  
  <p>Tried to reboot a hundred times, tried SSH-1 RSA, tried public key instead of private key, tried keys with passphrase, tried everything.</p>
  
  <p>Someone else is experiencing this?</p>
  
  <p><strong>Edit:</strong></p>
  
  <p>Thought it might be a security problem, here are my rules if that helps:</p>
