The REST API encountered an error

Most likely caused by this https://github.com/WordPress/Requests/issues/838

Hy william here. It looks like you’re encountering a cURL error 28, which is a timeout issue. This could be due to various reasons, and here’s a step-by-step approach to resolve it:

1. You can try increasing the cURL timeout value in your WordPress installation. This can be done by adding the following code to your theme’s functions.php file or in a custom plugin:
   
   add_filter(‘http_request_timeout’, function($timeout) { return 30; // Increase the timeout value to 30 seconds or adjust as needed });
   
2. Verify that your server has sufficient resources (CPU, memory) to handle the increased load. If your server is running out of resources, it can cause timeouts.
3. Deactivate your plugins one by one and check if the issue persists. Sometimes, a poorly coded or incompatible plugin can cause timeouts.
4. Switch to a default WordPress theme (like Twenty Twenty-One) to see if the problem persists. If the issue is theme-related, you might need to contact the theme developer for support.
5. Ensure that Plesk is properly configured and that there are no restrictions on outgoing connections or timeouts that could be affecting cURL requests.
6. If none of the above steps resolve the issue, contact your hosting provider’s support. They can check server logs and provide insights into any server-side issues.
   
   Remember to back up your site before making any changes. If the problem persists, reaching out to your hosting support is crucial, as they can provide specific insights into server-related issues. Let me know how it goes.
