title: can't push/pull from mercurial repository - abort: error: An existing connection was forcibly closed by the remote host
body: <p>I am planning to use mercurial for a new project but I'm having some problem accessing the bitbucket repository. I'm new to mercurial, but I have used git previously.</p>
  
  <p>I get the following error when peforing a hg clone or push:</p>
  
  <p><em>abort: error: An existing connection was forcibly closed by the remote host</em></p>
  
  <p>I only have this problem when using my work pc, when accessing the repository from my home pc I can clone and push just fine, any ideas, is there some firewall setting that needs to be configured?</p>
  
  <p>I'm using Mercurial-2.1.2-x64 on windows 7 x64 for both pcs.</p>
