Wordpress Can'；除非通过专用IP，否则无法访问nginx web服务器

对不起，如果这个问题已经被问了一百万次了，但我还没有找到答案

我正在尝试在我的计算机上托管一个wordpress站点，它运行ubuntu服务器20.04，我使用Nginx作为web服务器。到目前为止，我已经成功地使用专用IP地址192.168.0.16在我的浏览器上建立了wordpress站点：

然而，当我尝试转到我在123-reg.co.uk上购买的实际域名时，没有返回任何内容。在123-reg.co.uk DNS管理页面中，我设置了两个A记录

DNS ENTRY   TYPE    PRIORITY    TTL DESTINATION/TARGET
*           A                       <my public ip>
@           A                       <my public ip>

这是我的/etc/nginx/sites available/文件：

server {
  listen 80;
  server_name www.<my domain name> <my domain name>;

  root /var/www/wordpress/public;
  index index.php;

  access_log /var/www/wordpress/logs/access.log;
  error_log /var/www/wordpress/logs/error.log;

  location / {
    try_files $uri $uri/ /index.php?$args;
  }

  location ~ \.php$ {
    include snippets/fastcgi-php.conf;
    fastcgi_pass unix:/run/php/php7.4-fpm.sock;
  }
}

我猜我在某个地方遗漏了一步，但我对这方面没有经验。 任何帮助都将不胜感激，我完全不知道下一步该怎么办
