title: gitlab empty response from server while clonning repository
body: <p>I just installed gitlab server and it is running with default configuration, I created a public visibility project called <code>test</code> and I went to another machine on the same network and tried to clone it but I keep getting the error </p>
  
  <pre><code>    developer@ItnowDev:/apps/html$ git clone http://IP-OF-SERVER/USER/test.git
  Cloning into 'test'...
  fatal: unable to access 'http://IP-OF-SERVER/USER/test.git/': Empty reply from server
  </code></pre>
  
  <p>I am using 2.9.0 git to connect to gitlab server and the gitlab server is using http port, I can reach the gitlab server through my web browser but cannot do it on cli, what am I missing? does cli uses any other port protocol that could be blocked by firewalls?</p>
