title: No supported authentication methods available
body: <p>I am unable to logon to my GCE VM instance, what I did was following:</p>
  
  <ol>
  <li>Use PuTTY Key Generate to generate a public key and a private key.</li>
  <li>I copied public key in Metabase section under Developers Console. Followed the format username:. Something like:</li>
  </ol>
  
  <p>Administrator:ssh-rsa AAAAB3NzaC1yc2EAAAABJQAAAQEAiNbeEUl.......</p>
  
  <p>I am sure there is no new line problem with my copy/paste.</p>
  
  <ol>
  <li>I loaded my private key using PuTTY but I am receiving following error:</li>
  </ol>
  
  <p><strong>Disconnected: No supported authentication methods available(server sent: publickey,gssapi-keyex,gssapi0with-mic)</strong></p>
  
  <p>In the event log, it reads:</p>
  
  <p><strong>Offered public key
  Server refused our key</strong></p>
  
  <h1>Help needed:</h1>
  
  <p>The steps are pretty straight forward and the error is very general. I basically tried steps I can find on internet but still no go. </p>
  
  <p>Not sure how can I move forward??</p>
