Error: [] cURL error 28: Operation timed out after 10000 milliseconds with 0 bytes received * and * **The loopback request to your site failed, this means features relying on them are not currently working as expected. Error encountered: (0) cURL error 28: Operation timed out after 10001 milliseconds with 0 bytes received * Turned off all plugins, restared one by one, only happens when Woocommerce is activated * Any help would be appreciated * Thanks, Martin Viewing 15 replies - 1 through 15 (of 18 total) 1 [2](https://wordpress.org/support/topic/rest-api-error-12/page/2/?output_format=md) [→](https://wordpress.org/support/topic/rest-api-error-12/page/2/?output_format=md) * Plugin Support [Riaan K.](https://wordpress.org/support/users/riaanknoetze/) * (@riaanknoetze) * [6 years ago](https://wordpress.org/support/topic/rest-api-error-12/#post-12869473) * Hi there, * This sounds like it’s hosting-related more than an issue with WooCommerce itself; Just to make sure – have you checked with your hosting provider on whether loopback connections are allowed? * Thread Starter [customgearuk](https://wordpress.org/support/users/customgearuk/) * (@customgearuk) * [6 years ago](https://wordpress.org/support/topic/rest-api-error-12/#post-12869499) * I have full cPanel access can I check this myself? * Thread Starter [customgearuk](https://wordpress.org/support/users/customgearuk/) * (@customgearuk) * [6 years ago](https://wordpress.org/support/topic/rest-api-error-12/#post-12869500) * Server architecture Linux 2.6.32-896.16.1.lve1.4.49.el6.x86_64 x86_64 Website server user XXXXXX (854) Web server Apache PHP version 7.3.17 (Supports 64bit values) PHP SAPI litespeed PHP max input variables 1000 PHP time limit 600 PHP memory limit 300M Max input time 600 Upload max filesize 256M PHP post max size 300M cURL version 7.70.0 OpenSSL/1.1.1g Is SUHOSIN installed?

I basically had a subscription with Jetpack and had lots of trouble since then, . I gave up on it and raised a support request. * Thread Starter [customgearuk](https://wordpress.org/support/users/customgearuk/) * (@customgearuk) * [6 years ago](https://wordpress.org/support/topic/rest-api-error-12/#post-12869549) * Nope still getting error… * [kritinet](https://wordpress.org/support/users/kritinet/) * (@kritinet) * [6 years ago](https://wordpress.org/support/topic/rest-api-error-12/#post-12869637) * I have the same issue. Although i have woocommerce installed, this doesn’t seem to be the problem. I am using Setsail Theme. With this theme i need a plugin called “Tours” which i obviously need while using the theme. Untill a couple of days ago all was fine, but now receiving the same error as mentioned above. When i DE-Activate the TOUR plugin, error is gone. As soon as i activate the plugin again, the error is there again. I read somewhere that it could have something to do with an update within WordPress ? No clue so far… * Max - This reply was modified 6 years ago by [kritinet](https://wordpress.org/support/users/kritinet/). * Thread Starter [customgearuk](https://wordpress.org/support/users/customgearuk/) * (@customgearuk) * [6 years ago](https://wordpress.org/support/topic/rest-api-error-12/#post-12869645) * Irritating!!!!! * Thread Starter [customgearuk](https://wordpress.org/support/users/customgearuk/) * (@customgearuk) * [6 years ago](https://wordpress.org/support/topic/rest-api-error-12/#post-12876330) * ANY HELP???? * [kritinet](https://wordpress.org/support/users/kritinet/) * (@kritinet) * [6 years ago](https://wordpress.org/support/topic/rest-api-error-12/#post-12878831) * I didn’t come forward also…seems like we have to wait forever for an answer.

Here is a very good write up: [https://wordpress.org/support/topic/the-loopback-request-to-your-site-failed-4/page/2/](https://wordpress.org/support/topic/the-loopback-request-to-your-site-failed-4/page/2/) * But apart from the errors, do you have any problems executing stuff i.e. for example making REST API calls from your client? Because the error messages are mostly for internal use.
