Whilst configuring the Linode box running this site’s new setup, I eventually abandoned a bug in my NGINX config that was proving problematic.

The issue was this: Though port 80 had the following settings in its server block, the Observatory’s tests were telling me that http traffic wasn’t being redirected to https.

server {
    listen 80 default_server;
    listen [::]:80 default_server;

    server_name elliotekj.com www.elliotekj.com;
    return 301 https://$host$request_uri;
}

This evening I revisited said bug with fresh eyes and, as happens so often in software development, quickly saw the mistake I had made: I had placed the SSL configuration options outside of the server block for port 443.

Simply moving ssl on and company into the correct server block — the one for port 443 — turned the http to https redirect test green.
