## Redirects all HTTP traffic to the HTTPS host

  ## Either remove "default_server" from the listen line below,
  ## or delete the /etc/nginx/sites-enabled/default file. This will cause gitlab

  ## the ip address of the server (http://x.x.x.x/)

  ## Replace this with something like pages.gitlab.com
