sirfpsycho Hello, try the following format restrictions.
Among them, the allow part can be limited to the IP that can access the landing page. After modification, reload nginx again.
location = /wp-login.php
{
fastcgi_pass 127.0.0.1:9000;
fastcgi_index index.php;
include fcgi.conf;
allow 192.168.9.0/24;
deny all;
}
