Prevent HTTPS to HTTP redirect on nginx AWS?

Question

I have a wordpress site with nginx packed into a Docker image behind an AWS ELB Load Balancer. Only HTTPS is enabled on the load balancer.

When I access the URL: https://example.com/wp-admin/ it works fine but when I access the URL:

https://example.com/wp-admin the server fails as it tries to redirect to url: http://example.com/wp-admin/

I found this thread which has similar issue and applies all three possible solution options suggested but it didn't workout for me.

Here is my nginx config file for the site

How do I prevent the HTTPS to HTTP redirect or redirect from HTTPS to HTTPS e.g: https://example.com/wp-admin to https://example.com/wp-admin/

My wp-config.php

Answer 1

Adding:

absolute_redirect off; if ($http_x_forwarded_proto = "http") { return 301 https://$host$request_uri; } 

in my nginx config file for the site solved the issue for me.
