GitLab Unicorn web server is not running
<p>I installed gilab using these instructions: <a href="https://gitlab.com/gitlab-org/gitlab-ce/blob/master/doc/install/installation.md" rel="nofollow">gitlab.com</a></p>

<p>When gitlab start, I get a message in the console: The GitLab Unicorn web server is not running.</p>

<p>When I go to server, in the browser i get 502 error. </p>

<p>It is <code>unicorn.stderr.log</code>: <a href="https://plnkr.co/edit/aIvTjKqUgPItyvESsH3S?p=catalogue" rel="nofollow">link to plunker</a></p>

<p>This error can occur because of what?</p>
