Homepage Cache Keeps Rebuilding

Hi, noticed the homepage keeps rebuilding the cache on each page load. I've set cache timeout and garbage collection, unchecked cache from clearing on page changes, unchecked homepage checking. I've also removed $args from the location block in the server config. The other pages will cache and expire accordingly as I've set it up. Just not the homepage. Also noticed if I add a trailing period or variable to the homepage URL, the cache also functions properly for that URL. Any ideas?

The permalink format is currently '/%postname%/%post_id%' and WP was installed manually. Here's the format of my nginx CONF

Code:

server {
    server_name website.com www.website.com;
    return 302 https://$server_name$request_uri;
}
server {
  listen 443 ssl http2;
  server_name website.com www.website.com;
  ssl_dhparam /usr/local/nginx/conf/ssl/website.com/dhparam.pem;
  ssl_certificate      /usr/local/nginx/conf/ssl/website.com/ssl-unified.crt;
  ssl_certificate_key  /usr/local/nginx/conf/ssl/website.com/website.com.key;
  ssl_prefer_server_ciphers on;
  ssl_buffer_size 1400;
  ssl_session_tickets on;
  include /usr/local/nginx/conf/ssl_include.conf;
  root /home/nginx/domains/website.com/public;
  location / {
  try_files /wp-content/cache/supercache/$http_host/$cache_uri/index.html $uri $uri/ /index.php?q=$uri&$args;
  }
  location ~ ([^/]*)sitemap(.*)\.x(m|s)l$ {
  rewrite ^/sitemap\.xml$ /sitemap_index.xml permanent;
  rewrite ^/([a-z]+)?-?sitemap\.xsl$ /index.php?xsl=$1 last;
  rewrite ^/sitemap_index\.xml$ /index.php?sitemap=1 last;
  rewrite ^/([^/]+?)-sitemap([0-9]+)?\.xml$ /index.php?sitemap=$1&sitemap_n=$2 last;
  }
  include /usr/local/nginx/conf/wpsecure.conf;
  include /usr/local/nginx/conf/wpsupercache.conf;
  include /usr/local/nginx/conf/php-wpsc.conf;
  include /usr/local/nginx/conf/staticfiles.conf;
  include /usr/local/nginx/conf/drop.conf;
  include /usr/local/nginx/conf/vts_server.conf;
}

Here's wpsupercache.conf:

Code:

set $cache_uri $request_uri;


# POST requests and urls with a query string should always go to PHP

if ($request_method = POST) {

        set $cache_uri 'null cache';

}


if ($query_string != "") {

        set $cache_uri 'null cache';

}


# Don't cache uris containing the following segments

if ($request_uri ~* "(/add-a-quote|/random-story|/contact-form|/wp-admin/|/xmlrpc.php|/wp-(app|cron|login|register|mail).php|wp-.*.php|/feed/|index.php|wp-comments-popup.php|wp-links-opml.php|wp-locations.php|sitemap(_index)?.xml|[a-z0-9_-]+-sitemap([0-9]+)?.xml)") {

        set $cache_uri 'null cache';

}


# Don't use the cache for logged in users or recent commenters

if ($http_cookie ~* "comment_author|wordpress_[a-f0-9]+|wp-postpass|wordpress_logged_in") {

        set $cache_uri 'null cache';

}

 

Tried clearing cache again and I still get this on page load.

<!-- Dynamic page generated in 0.564 seconds. -->
<!-- Cached page generated by WP-Super-Cache on 2016-04-11 15:52:55 -->
<!-- Compression = gzip -->

 

Yup I followed the instructions for that page.

And I moved the conf above the root/location block and it's still doing it. Says it's cached in the HTML. But the thing is, if I turn off PHP, the page isn't cached and won't load. But the homepage and others that I haven't set in the config will work.

If that's all set properly, any other ideas?
