title: Openshift- git clone gives Permission denied (publickey,gssapi-keyex,gssapi-with-mic)
body: <p>I have created a new account with openshift online and have created my first app. I have <code>rhc</code> installed on my local machine. I setup ssh keys for the first time using <code>rhc setup -l loginname</code>
  i used git clone to clone the remote repo and it worked fine. Then however after changes and tring to do a git push gave me the following error:</p>
  
  <pre><code>Permission denied (publickey,gssapi-keyex,gssapi-with-mic).
  fatal: Could not read from remote repository.
  Please make sure you have the correct access rights
  </code></pre>
  
  <p>I tried a couple of solutions provided in this forum like using <code>ssh-add</code> etc. but this did not work.I then made sure that all existing ssh keys under <code>.ssh</code> directory and from my openshift online account were deleted and all identities managed by ssh-agent were also deleted. I then launched <code>rhc setup</code> again This created the default ssh keys again and asked me if it could upload the public key which I selected yes to. 
  However then it gives me the following error:</p>
  
  <pre><code>An SSH connection could not be established to appname-domain-name.rhcloud.com.
  Your SSH configuration may not be correct, or the application may not be
  responding. connection closed by remote host (Net::SSH::Disconnect)
  </code></pre>
  
  <p>Kindly help.</p>
