NGINX reverse proxy setup

This is a very basic config, secured with Let's Encrypt. Any log is disabled by default. Do not forget to replace server_name with your domain.

server {
    listen 80;
    listen [::]:80;
    listen 443 ssl;
    listen [::]:443 ssl;
        http2 on;

    server_name invidious.domain.tld;

    access_log off;
    error_log /var/log/nginx/error.log crit;

    ssl_certificate /etc/letsencrypt/live/invidious.domain.tld/fullchain.pem;
    ssl_certificate_key /etc/letsencrypt/live/invidious.domain.tld/privkey.pem;

    location / {
        proxy_pass http://127.0.0.1:3000;
        proxy_set_header X-Forwarded-For $remote_addr;
        proxy_set_header Host $host;    # so Invidious knows domain
        proxy_http_version 1.1;     # to keep alive
        proxy_set_header Connection ""; # to keep alive
    }

    if ($https = '') { return 301 https://$host$request_uri; }  # if not connected to HTTPS, perma-redirect to HTTPS
}
