Title: Error message cURL error 28: http_request_failed Last modified: April 15, 2020 --- # Error message cURL error 28: http_request_failed * [alfateefje](https://wordpress.org/support/users/alfateefje/) * (@alfateefje) * [6 years, 1 month ago](https://wordpress.org/support/topic/error-message-curl-error-28-http_request_failed/) * Hi I am using your plugin on my website, calculating the price of orders. It’s working ok. I like its simplicity and it is easy to use 😉 But in my ‘Site diagnose’ I get this _critical_ error message: `"cURL error 28: Operation timed out after 10000 milliseconds with 0 bytes received (http_request_failed)".` Deactivating the plugin makes this error message go away, but that’s not what I want. Any ideas how to solve this out? Kind regards, Susan Viewing 5 replies - 1 through 5 (of 5 total) * [ladislavprokop](https://wordpress.org/support/users/ladislavprokop/) * (@ladislavprokop) * [6 years ago](https://wordpress.org/support/topic/error-message-curl-error-28-http_request_failed/#post-12768068) * Hi there, * I have same issue at my page: [https://www.flyboards.cz](https://www.flyboards.cz).

One example is the block editor screen, which relies on this to display, and save, your posts and pages. * The REST API request failed due to an error. Error: cURL error 28: Operation timed out after 10001 milliseconds with 0 bytes received (http_request_failed)” * Deactivating plugins is also not helpful. Please suggest a solution to this problem? * [janv01](https://wordpress.org/support/users/janv01/) * (@janv01) * [5 years, 11 months ago](https://wordpress.org/support/topic/error-message-curl-error-28-http_request_failed/#post-13045760) * Same here: cURL error 28: Operation timed out after 10001 milliseconds with 0 bytes received (http_request_failed) Is there a solution? Deactivating the plugins solves it, so I guess the problem is caused by the plugin. * [swmchau](https://wordpress.org/support/users/swmchau/) * (@swmchau) * [5 years, 7 months ago](https://wordpress.org/support/topic/error-message-curl-error-28-http_request_failed/#post-13500119) * Same, received message: Error: cURL error 28: Operation timed out after 10000 milliseconds with 0 bytes received (http_request_failed) Now the plugin is deactivated.
