NGINX Multi Site * SSL 子域：配置文件错误：[emerg] 0.0.0.0:443 的重复监听选项

Question

目前正在 NGINX、Ubuntu 22.04 Vultr 服务器上安装 SSL。我在服务器上有两个现有域。为 Wordpress 多站点（子域基础）设置通配符 SSL，并且在 /sites-available/ 文件夹中设置我的网站配置文件时遇到困难。

我不确定如何解决这个问题。

我通过以下方式安装了 certbot

sudo certbot certonly --manual --preferred-challenges dns --server https://acme-v02.api.letsencrypt.org/directory -d '*.gethisyes.com' -d gethisyes.com

我将 TXT 记录质询添加到我的 DNS。一切顺利。

但现在尝试设置配置文件时，我收到“重复监听”选项错误。我不确定如何为 wordpress 多站点域设置通配符 SSL 的配置文件。

这是我当前的 /sites-available/site.com.conf 配置文件。

map $http_host $blogid {
    default       -999;
}

server {

 listen 80;
  server_name example.com *.example.com;
       return 301 http://example.com$request_uri;
}

server {
    listen 443 http2 ssl backlog=4096;

    server_name example.com *.example.com;
    root /var/www/example.com/public_html;
    index index.php;

    location / {
        try_files $uri $uri/ /index.php$is_args$args;

    }

        location ~ ^/files/(.*)$ {
                try_files /wp-content/blogs.dir/$blogid/$uri /wp-includes/ms-files.php?file=$1 ;
                access_log off; log_not_found off;      expires max;
        }

        #WPMU x-sendfile to avoid php readfile()
        location ^~ /blogs.dir {
                internal;
                alias /var/www/example.com/html/wp-content/blogs.dir;
                access_log off;     log_not_found off;      expires max;

        }
        include /etc/nginx/ssl/ssl_example.com.conf;
        include /etc/nginx/ssl/ssl_all_examples.conf;

    location ~ \.php$ {
        include snippets/fastcgi-php.conf;
        fastcgi_pass unix:/run/php/php8.1-fpm.sock;
        include /etc/nginx/includes/fastcgi_optimize.conf;

    }

    include /etc/nginx/includes/browser_caching.conf;
    access_log /var/log/nginx/access_example.com.log combined buffer=256k flush=60m;
    error_log /var/log/nginx/error_example.com.log;

}

当我测试 nginx 配置文件时出现此错误

nginx: [emerg] duplicate listen options for 0.0.0.0:443 in /etc/nginx/sites-enabled/gethisyes.com.conf:13
nginx: configuration file /etc/nginx/nginx.conf test failed
