Recently, I had issues with nginx placing the port number after redirects if the URL was missing the trailing slash (for example: https://example.com/thing would redirect to https://example:8080/thing/). So, I added the line for port_in_redirect off; and that fixed the issue. However, it's now causing another issue. If the url is missing the trailing slash, it redirects to HTTP.

https://example.com/thing will redirect to http://example/thing/, which causes a failed request.

This is what my nginx.conf looks like:

#user  nobody;
worker_processes  1;

#error_log  logs/error.log;
#error_log  logs/error.log  notice;
error_log  /var/log/error.log  info;

#pid        logs/nginx.pid;


events {
    worker_connections  1024;
}
