 * Hello there,
 * Recently I have noticed an error in the Site Health section. It’s the first time
   I am having such an error. I spent a couple of nights on this error but can not
   find a solution.
 * For a long time, I have been using the same set of plugins. But recently wanted
   to test some other caching plugins rather than my default Cache Enabler plugin.
   I tried LiteSpeed Cache, then gave up. My first thought was maybe it was because
   of this plugin change, but when I asked them, they confirmed that they didn’t
   have any injected left-over code for settings.
 * The REST API encountered an error
    Performance The REST API is one way WordPress,
   and other applications, communicate with the server. 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: Connection
   timed out after 10000 milliseconds (http_request_failed)
 * Your site could not complete a loopback request
    Performance Loopback requests
   are used to run scheduled events and are also used by the built-in editors for
   themes and plugins to verify code stability.
 * The loopback request to your site failed, this means features relying on them
   are not currently working as expected.
    Error: cURL error 28: Connection timed
   out after 10001 milliseconds (http_request_failed)
 * I also installed Query Monitor and checked it on the Site Health page and have
   these results below.
 * I mean I’m pretty technical in comparison to a beginner WP user but this is still
   taking me ages to figure out what’s happening. There were even people recommending
   a new website install which must be a joke as it’s a live site with many active
   visitors.
 * Wouldn’t it be better if Site Health could really point an issue for inspection
   rather than just giving us regular users a general statement?
 *     ```
       GET	https://cigilovic.com/wp-json/wp/v2/types/post
       ?context=edit	cURL error 28: Connection timed out after 10000 milliseconds
       WP_Site_Health->get_test_rest_availability()
       wp-admin/includes/class-wp-site-health.php:2031
       WP_Site_Health->perform_test()
       wp-admin/includes/class-wp-site-health.php:177
       WP_Site_Health->enqueue_scripts()
       wp-admin/includes/class-wp-site-health.php:122
       do_action('admin_enqueue_scripts')
       wp-includes/plugin.php:484
       ```
   
 * Can anyone support me in diagnosing this problem, please? Internet is full of
   people having the same problem, but none of the solutions worked for me.
 * Many thanks
 * Osman
