Enable SSL for whole Drupal 8 site I'm running a Drupal 8 site behind a nginx webserver. All http request are redirected to https. My problem is that rss links on that site are http links only.

With Drupal 7 by setting the base_url all links are shown as https links. In Drupal 8 this option is missing. How can I set the whole site to https? Is there a config option for setttings.php?
Depending on how the RSS links are rendered, I would suggest calling them over with a protocol-relative URL such as:

//domain.com/rss-feed....


This will force the information to be sent over based on the way the page was rendered.  If the page was rendered using https:// it will use https:// in place of '//'
