title: Git clone error "HTTP code 504 from proxy after CONNECT"
body: <p>I'm working in a office behind a corporate firewall.  My System is windows7, using componentes consola. Usually I need to set up proxy connections to get GIT working with github.</p>
  
  <p>But when I try to clone a repository sored in a private Stash (Atlassian) I get this error:</p>
  
  <pre><code>Cloning into 'apptest'...
  fatal: unable to access 'https://xxx@xxx.xx.xx.xx:xxxx/apptest/apptest.git
  /': Received HTTP code 504 from proxy after CONNECT
  </code></pre>
  
  <p>I have unsetted git proxy but I'm still facing same problem.
  Please note that I'm using GITshell over Windows 7</p>
  
  <p>Any help would be appreciated.</p>
  
  <p>Regards</p>
