title: Bitbucket ssh test returns `remote: ssh_exchange_identification: read: Operation timed out`
body: <p>I am setting up a new machine and in doing so, was trying to pull repos from bitbucket, which does not work for either git or hg. I have added my public key to bitbucket.</p>
  
  <p>This is what I see when I run the debugging command that bitbucket suggests in the troubleshooting guide:</p>
  
  <pre><code>$ ssh -Tv hg@bitbucket.org
  OpenSSH_6.9p1, LibreSSL 2.1.8
