There is some information on https://www.drupal.org/https-information about installing the Secure Pages module to force SSL. This gives me a redirect loop on the login pages.
When I try without the Secure Login module I get mixed mode errors due to JS being served in plain http. Is a module really the only method to enable SSL on D8?
Assuming the server configuration is set-up for HTTPS and has the relevant SSL certifications and settings: Specifically, with the Drupal configuration, what is the correct way to make a Drupal 8 site Https only?
