title: Yuk- Chan Docker image in GitLab
body: <p>I was using the Docker image of Yuki-Chan in GitLab but i'm having some troubles. 
  I get recurrent this error:</p>
  
  <pre><code>requests.exceptions.ConnectionError: HTTPConnectionPool(host='https', port=80): Max retries exceeded with url: //target (Caused by NewConnectionError('&lt;urllib3.connection.HTTPConnection object at 0x7f10e72d7190&gt;: Failed to establish a new connection: [Errno -2] Name or service not known',))
  </code></pre>
  
  <p>do you any idea about the cause?</p>
  
  <p>Thank you very much!</p>
