uri – Drupal and reverse proxy: How to make Drupal aware that it’s protocol is HTTPS?

I have a reverse proxy Docker container in front a Drupal container on a Docker host.

My reverse proxy container is https://hub.docker.com/r/jwilder/nginx-proxy

The public site URL is https://ahora-stage2.dcycleproject.org

When a request is made to https://ahora-stage2.dcycleproject.org, drupal receives the following headers. I ran dpm(Drupal::request()->headers); using devel/php on a backend web interface:

stdClass Object ( (__CLASS__) => SymfonyComponentHttpFoundationHeaderBag (headers:protected) => Array ( (authorization) => Array ( (0) => ) (host) => Array ( (0) => ahora-stage2.dcycleproject.org ) (connection) => Array ( (0) => close ) (x-real-ip) => Array ( (0) => 216.246.250.184 ) (x-forwarded-for) => Array ( (0) => 216.246.250.184 ) (x-forwarded-proto) => Array ( (0) => https ) (x-forwarded-ssl) => Array ( (0) => on ) (x-forwarded-port) => Array ( (0) => 443 ) (content-length) => Array ( (0) => 212 ) (accept) => Array ( (0) => text/html,application/xhtml+xml,application/xml;q=0.9,*/*;q=0.8 ) (content-type) => Array ( (0) => application/x-www-form-urlencoded ) (origin) => Array ( (0) => https://ahora-stage2.dcycleproject.org ) (accept-language) => Array ( (0) => en-ca                 ) (user-agent) => Array ( (0) => Mozilla/5.0 (Macintosh; Intel Mac OS X 10_15_6) AppleWebKit/605.1.15 (KHTML, like Gecko) Version/14.0.3 Safari/605.1.15 ) (referer) => Array ( (0) => https://ahora-stage2.dcycleproject.org/devel/php ) (accept-encoding) => Array ( (0) => gzip, deflate, br ) (cookie) => Array ( (0) => SESS06c9cc57c2abbd62a4b35358c6967749=zmOe3Gexxxxxxxx7238990ldZb50rMxl35yPOeM ) (x-php-ob-level) => Array ( (0) => 0 ) ) (cacheControl:protected) => Array ( ) ) 

Based on that information, https://x-team.com/blog/base_url-drupal-8/, https://medium.com/@lmakarov/drupal-8-and-reverse-proxies-the-base-url-drama-c5553cbc9a3e, and comments in the settings.php file, I put these custom settings in my Drupal settings.php file:

$settings('reverse_proxy') = TRUE;
$settings('reverse_proxy_addresses') = ('104.236.70.29','216.246.250.184');

Nonetheless, Drupal always keep believing that the protol is HTTP, not HTTPS.

I’m wondering how I could set it up so that Drupal understands that it’s behind a reverse proxy and that it’s public URL should be served using the https protocol.
