title: How to setup Codeception with remote code coverage?
body: <ul>
  <li>I have two repo on my machine
  
  <ol>
  <li>API </li>
  <li>Codeception repo that tests API</li>
  </ol></li>
  </ul>
  
  <p>In API repo I have added codeception+c3</p>
  
  <pre><code>"require-dev": {
      "codeception/codeception": "2.*",
      "codeception/c3": "2.*",
  </code></pre>
  
  <p>I've also included c3.php inside index.php, but when trying to test it with --coverage I have this error </p>
  
  <p>[PHPUnit_Framework_Exception]
    file_get_contents(<a href="http://local.api.codeception.com/c3/report/clear" rel="noreferrer">http://local.api.codeception.com/c3/report/clear</a>): fai
    led to open stream: HTTP request failed! HTTP/1.1 500 Internal Server Error</p>
  
  <p>Is there <em>ANY</em> online example of remote codecoverage with Codeception?</p>
