Password Protect Login URL

Hi,

I have a setup that hide my login url using the plugin.
And now, I am trying to add an extra security layer using http password protect, but it seems didn’t work with my usual code :

location ^~ wp-login\.php$ {
    auth_basic "Authorization Required";
    auth_basic_user_file /var/www/.htpasswd;
    try_files $uri =404;
    fastcgi_pass php7;
    fastcgi_index  index.php;
    fastcgi_read_timeout 300;
    include fastcgi_params;
}

Or do I need to make change of the code?
