Nginx禁用IP方式通过443/80端口访问网站，也可以屏蔽其它的域名解析到你的网站IP。

加一个server块，server_name _;

return 403; 或者301引流到指定URL

server {
        listen 80 default;
        listen 443 default_server;
        server_name _;
        ssl_certificate /usr/local/nginx/conf/ssl/www.example.com.cer;
        ssl_certificate_key /usr/local/nginx/conf/ssl/www.example.com.key;
        ssl_protocols TLSv1 TLSv1.1 TLSv1.2 TLSv1.3;
        ssl_ciphers TLS13-AES-256-GCM-SHA384:TLS13-CHACHA20-POLY1305-SHA256:TLS13-AES-128-GCM-SHA256:TLS13-AES-128-CCM-8-SHA256:TLS13-AES-128-CCM-SHA256:EECDH+CHACHA20:EECDH+AES128:RSA+AES128:EECDH+AES256:RSA+AES256:EECDH+3DES:RSA+3DES:!MD5;
        ssl_prefer_server_ciphers on;
        ssl_session_timeout 10m;
        ssl_session_cache builtin:1000 shared:SSL:10m;
        return 403;
       }
