Nginx auth basic won’t work for wordpress wp-login.php

I have used several rules to block wp-login.php with a htpassword. The htpassword module is working. I added it to root of the site and it worked. But wp-login.php is not working. Here’s my website http://www.digitalreborn.com/wp-admin

Here’s the passwd rule :

location ~* /wp-login.php {
    auth_basic            "Restricted Area: WordPress";
    auth_basic_user_file  /var/www/digitalreborn/.htpasswd;

    try_files $uri =404;
    fastcgi_pass unix:/var/run/php5-fpm.sock;
    fastcgi_index index.php;
    include fastcgi_params;

}
