I’m running a lot of services off my nginx reverse proxy. This is my general setup for each subdomain - each in its own config file. I wouldn’t consider this verbose in any way - and it’s never crashed on me

service.conf

server {
    listen       443 ssl http2;
    listen  [::]:443 ssl http2;
    server_name  [something].0x-ia.moe;

    include /etc/nginx/acl_local.conf;
    include /etc/nginx/default_settings.conf;
    include /etc/nginx/ssl_0x-ia.conf;

    location / {
        proxy_pass              http://[host]:[port]/;
    }
}

http3 is available in nginx 1.25 if you want to run their current release.
