This should work fine, what server type you run? Does your site run behind a proxy? Do you use a CDN service? Does the Cron call is actually internally or being triggered remotely?

I see another IP from my provider’s cluster appears often. I add it in htaccess rules: * ``` RewriteCond %{REMOTE_ADDR} !^MY\SERVER\IP$ RewriteCond %{REMOTE_ADDR} !^ANOTHER\CLUSTER\IP$ RewriteRule ^wp-cron.php /index.php?wph-throw-404 [L] ``` * And it works =o * Maybe the web application firewall from the infrastructure or anything else. * Plugin Contributor [Maya](https://wordpress.org/support/users/tdgu/) * (@tdgu) * [6 years, 5 months ago](https://wordpress.org/support/topic/block-wp-cron-php-issue/#post-12265610) * Hi, That’s correct, only the IP which is being reported by by the server through php is being white-listed. Your solution ( the extra conditional in rewrite) is correct. * Thanks Viewing 9 replies - 1 through 9 (of 9 total) The topic ‘Block wp-cron.php issue’ is closed to new replies. * ![](https://ps.w.org/wp-hide-security-enhancer/assets/icon-256x256.png?rev=2937681) * [WP Hide & Security Enhancer](https://wordpress.org/plugins/wp-hide-security-enhancer/) * [Frequently Asked Questions](https://wordpress.org/plugins/wp-hide-security-enhancer/#faq) * [Support Threads](https://wordpress.org/support/plugin/wp-hide-security-enhancer/) * [Active Topics](https://wordpress.org/support/plugin/wp-hide-security-enhancer/active/) * [Unresolved Topics](https://wordpress.org/support/plugin/wp-hide-security-enhancer/unresolved/) * [Reviews](https://wordpress.org/support/plugin/wp-hide-security-enhancer/reviews/) * 9 replies * 2 participants * Last reply from: [Maya](https://wordpress.org/support/users/tdgu/) * Last activity: [6 years, 5 months ago](https://wordpress.org/support/topic/block-wp-cron-php-issue/#post-12265610) * Status: resolved
