Title: Page Cache Preload + SSL Not Working Last modified: April 24, 2020 --- # Page Cache Preload + SSL Not Working * Resolved [savingsbazar](https://wordpress.org/support/users/savingsbazar/) * (@savingsbazar) * [6 years, 1 month ago](https://wordpress.org/support/topic/page-cache-ssl-not-working/) * Hello Team, * I hope W3 Team is keeping fine in these tough times. I just migrated from http to https for my website. Page Cache was working perfectly with auto preload on HTTP, however after I shifted to https Preloading of SSL Pages is not working. I have enabled the option Cache SSL (HTTPS) requests (Cache SSL requests (uniquely) in page cache for improved performance). However, preloading of HTTPS (SSL) pages does not work. So I cloned my website and again tried to recheck whether preloading works on http (Non-SSL) version, and it works. * Page Cache is working with HTTPS only when a visitor visits the page (The cache gets generated only when a customer visits that link), It does not get generated automatically even though Cache Preload is enabled with Automatic Priming of Cache. So the issue is with preloading the HTTPS Pages. I want the HTTPS (SSL) Page cache to be preloaded. * Team, I am looking to reslove this issue ASAP. Can you please help me with this? - This topic was modified 6 years, 1 month ago by [savingsbazar](https://wordpress.org/support/users/savingsbazar/).

The problem is with the sitemap URL. your sitemap URL is `sitemap_index.xml` it should be like this: `https:// yourwebsite.com/sitemap_index.xml` * This is a full sitemap URL of your website and W3 Total Cache needs it to be able to cache the entire website.

However, same issue. * Plugin Contributor [Marko Vasiljevic](https://wordpress.org/support/users/vmarko/) * (@vmarko) * [6 years, 1 month ago](https://wordpress.org/support/topic/page-cache-ssl-not-working/#post-12738359) * Hello [@savingsbazar](https://wordpress.org/support/users/savingsbazar/) * What the Cache Preload does is this: – Check the last offset – Check how many URLs are allowed to be processed per run – Fetch all URLs from sitemap (even nested sitemaps work) – Loop through a set of URLs to visit them If the end of the list is reached, it will start from the beginning of the next run. Basically it’s like visiting the website to do what a real visitor would do otherwise. The cron job triggers the page cache generation, so the real visitors won’t experience any delay. The user agent used for the cronjob is “WordPress”, which is automatically ignored by Page Cache. So you may need to visit the page first to start the trigger the cron. Also, the interval of 120 s is to often so you should increase that to the default of 900s or at least 600s As two cron is not very reliable you can also disable it by adding `define('DISABLE_WP_CRON', true);` to your wp-config. php and Once this is done, you needs to create and Schedule System Cron that will call wp-cron.php at a set interval. you can do this on your host and the example is: `*/10 * * * * wget -q -O - http://www.example.com/ >/dev/null 2>& 1` In this case the cron job will be triggered every 10 minutes. * If you don’t want to rely on wp-cron – use wp-cli command for preloading and Unix cron `wp w3-total-cache pgcache_prime` This way you can also track the output which pages/sitemap positions are primed by script. * I hope this helps!
