Proxy

If you want to proxy the website through a webserver like nginx (e.g. for SSL or any other proxy such as Cloudflare), you will need to set the proxy config setting to true for certain parts of the website to function correctly (e.g. Ratelimiting, connection limits).

The below provided nginx sample config will proxy the website to https://domain.tld from http://domain.tld:port. As I don't know how to set this up for Apache, I cannot provide a working sample.

server {
    listen 80;
    listen [::]:80;
    server_name domain.tld; # Replace this with your actual domain

    return 301 https://$server_name$request_uri;
}

server {
    listen 443 ssl http2;
    listen [::]:443 ssl http2;

    server_name domain.tld; # Replace this with your actual domain

    ssl_certificate /location/of/certificate.pem;
    ssl_certificate_key /location/of/certificate.key;
    ssl_trusted_certificate /location/of/certificate.pem;
    # Get a certificate from e.g. Cloudflare or letsencrypt

    access_log /var/log/nginx/domain.tld.access.log;
    error_log /var/log/nginx/domain.tld.error.log;
    # Non vital, only if you want separate logging

    # SSL security settings omitted, but easy enough to find on the web

    location / {
        proxy_set_header X-Real-IP $remote_addr;
        proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for;
        proxy_set_header Host $host;
        proxy_set_header X-NginX-Proxy true;
        proxy_set_header Upgrade $http_upgrade;
        proxy_set_header Connection "Upgrade";
        proxy_http_version 1.1;
        proxy_store off;
        proxy_redirect off;
        proxy_pass http://127.0.0.1:<port>; # Replace port with configured port
    }
}
