tperrelli on "[Plugin: iThemes Security (formerly Better WP Security)] wp"

Hello, good day!

I don't know why, but nginx is rejecting http://mysite.com/wp-admin url
If i run: curl -I http://mysite.com/wp-admin url

i got this message:

HTTP/1.1 301 Moved Permanently
Server: nginx
Date: Thu, 28 Apr 2016 14:09:05 GMT
Content-Type: text/html
Content-Length: 178
Location: http://mysite.com/wp-admin/
Connection: keep-alive

If i access it from the browser, i can login normally... but when my browser get cache, the wp-login.php is being downloaded

I followed the itheme-security plugin steps as well.. so..
Is there any configuration that i did with no pay attention to cause this?
