title: can't connect to gitlab repository from VPS
body: <p>I'm using gitlab repository for version control.
  there is no problem when i run following commands on localhost.</p>
  
  <pre><code>$ git pull origin master
  
  $ git remote show origin
  
  $ git clone ...
  </code></pre>
  
  <p>but when i run same commands on my <code>vps</code> i get this error after about 20 seconds:</p>
  
  <blockquote>
    <p>ssh: connect to host gitlab.com port 22: Connection timed out fatal:
    The remote end hung up unexpectedly</p>
  </blockquote>
  
  <p>please tell me how to fix this.</p>
