PHP-FPM why get a redirect loop

Code:

server {
listen 127.0.0.1:8080;
   server_name DOMAIN www.DOMAIN;
#http2_max_field_size 16k;
 # http2_max_header_size 32k;

  root /home/nginx/domains/DOMAIN/public;
   index index.php;
   port_in_redirect off;

   location / {
      try_files $uri $uri/ /index.php?$args;
   }

  include /usr/local/nginx/conf/staticfiles.conf;

#a trial to include more php
####include /usr/local/nginx/conf/php-wpsc.conf;

 location ~ \.php$ {
 try_files $uri =404;
     fastcgi_split_path_info ^(.+\.php)(/.+)$;
       include fastcgi_params;
      fastcgi_index index.php;
       fastcgi_param SCRIPT_FILENAME $document_root$fastcgi_script_name;
       fastcgi_param HTTPS on;

        fastcgi_pass 127.0.0.1:9000;
}
}

THhe above server block which is the back end of varnoish works fine, do I need to put more security on it?
any way I tried to include the php-wpsc.conf; but I get "redirect loop"
