RSS Feed not working Drupal + Nginx + Boost Configuration

Hi,
I have been trying to figure this out but unable to fix this issue. I have setup and enabled Boost on Nginx and it works fine now but I cannot access my rss.xml file. It throws Nginx 404 Page not found error

Here is my Nginx Configuration file

server {
listen 80;
server_name www.pakreviews.com;
rewrite ^(.*) http://pakreviews.com$1 permanent;
}

server {
server_name www.pakreviews.com;
access_log /www/projects/pakreviews/logs/access.log;
error_log /www/projects/pakreviews/logs/error.log;
