title: Gitlab runner can not clone the repo
body: <p>I have a local Gitlab server installed via omnibus, let's call it gitlab.own.com , and I also have a gitlab-runner docker image where I want it to run the ci, they are both on the same machine. I have managed to register the runner but every time the ci runs I get this error:</p>
  
  <pre><code>Running with gitlab-runner 11.10.1 (1f513601) on runner11 mQZzHdu8

  <p>Any ideas what the problem might be?</p>
