Nginx получает доменное имя и ltd на основе простого регулярного выражения server_name

Я пытаюсь получить текущее доменное имя и ltd для текущего запроса, используя простое регулярное выражение для server_name. Проблема в том, что оно не устанавливает никаких переменных для $domain или $ltd.

server_name ~^(?<subdomain>[^\.]*)?(?<domain>[^\.]*)\.(?<tld>[^\.]*)$;

Мне нужно, чтобы переменные могли указывать на каталог ssl

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

полный код:

upstream web_backend {
    # Uncomment for the IP Hashing load balancing method:
    ip_hash;

    # Uncomment for the Least Connected load balancing method:
    # least_conn;

    # Replace the IP addresses with the IP addresses
    # (or host names) of your back end web servers.

    # Examples:
    # server 192.168.1.100;
    server x.x.x.x;
    server x.x.x.x;
}

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

    location ^~ /.well-known/acme-challenge/ {

        allow all;

        # Set correct content type. According to this:
        # https://community.letsencrypt.org/t/using-the-webroot-domain-verifi$
        # Current specification requires "text/plain" or no content header at$
        # It seems that "text/plain" is a safe option.
        default_type "text/plain";

        root /var/www/html;
    }

    # Hide /acme-challenge subdirectory and return 404 on all requests.
    # It is somewhat more secure than letting Nginx return 403.
    # Ending slash is important!
    location = /.well-known/acme-challenge/ {
            return 404;
    }

решение1

хорошо, я исправил проблему. основываясь на том, что сказал @RichardSmith. Шаги ниже:

1. In server block added = server_name _;
2. added $ssl_server_name to ssl_certificate and ssl_certificate_key
  A. ssl_certificate         /etc/letsencrypt/live/$ssl_server_name/fullchain.pem;
  B. ssl_certificate_key     /etc/letsencrypt/live/$ssl_server_name/privkey.pem;
3. In /etc/nginx/nginx.conf file change user to root or it will throw permission error.

Я использую версию Nginx: nginx/1.16.1
