{
    listen 80 default;
    listen 443 default_server;
    server_name _;
    return 403;
    ssl_certificate    ***.pem;  #随便找个pem
    ssl_certificate_key    ***.pem;
    ssl_protocols TLSv1.1 TLSv1.2 TLSv1.3;
    ssl_ciphers EECDH+CHACHA20:EECDH+CHACHA20-draft:EECDH+AES128:RSA+AES128:EECDH+AES256:RSA+AES256:EECDH+3DES:RSA+3DES:!MD5;
