使用HTTP基本身份验证时，Nginx重定向循环

Question

I'm trying to setup basic authentication for all of my site, but I'm getting a redirect loop when I try to enable it. Current config works, but when I add

auth_basic           "Secured";
auth_basic_user_file /var/www/*****/.htpasswd;

under location / {

it redirects endlessly to mysite.com/login and fails. mysite.com/login is the login page for the script I'm using, but it is not supposed to redirect there upon visiting the homepagepage and it does not do so normally. I am not sure if something in my script is causing the redirect loop, or my nginx config but I would like to figure a way to enable basic HTTP authentication.

Any ideas would be most appreciated, thank you.

    server_name  ***** www.*****;
