 * None of my scheduled actions are working on my site. Cron jobs are not happening,
   nothing is updating, and posts aren’t posting as scheduled. I am having to do
   everything manually and have been having this problem for weeks now. I’ve contacted
   my host and they say there is nothing on their end blocking scheduled actions.
   They suggested the problem is with the feedback loops within WordPress.
 * I have these errors under site health:
 * “Your site could not complete a loopback request. The loopback request returned
   an unexpected http status code, 403, it was not possible to determine if this
   will prevent features from working as expected.”
 * And another error: “Unable to detect page cache due to possible loopback request
   problem. Please verify that the loopback request test is passing. Error: Forbidden(
   Code: http_403)”

 * First off, please have a read of [https://developer.wordpress.org/advanced-administration/wordpress/loopback/](https://developer.wordpress.org/advanced-administration/wordpress/loopback/)
 * If troubleshooting recommended in the linked document doe not resolve the issue,
   then contact your hosting provider and ask them why loopback is failing.

 * You’re using Cloudflare, which handles all requests before they reach your website.
   I did a quick search on this, and their “Under Attack Mode” might be the cause.
   If you have any questions about this, it’s best to contact Cloudflare support:

 * No Cloudflare is not the issue; I have already checked with them and there are
   no bots running or anything else that is preventing scheduled events. They aren’t
   blocking anything, from what I can see.

 * I will look through the document you gave me t-p, thank you. But I will restate
   that I have already contacted my hosting provider and they are not the issue.

 * To rule out both the hosting provider and Cloudflare, you can also try moving
   the project. Just move the files and database to a different domain with a different
   hosting provider. If you encounter the same problem there, then it’s caused by
   a plugin. If you don’t have any problems there, then it’s caused by the hosting
   provider and/or Cloudflare.

 * Hi [@stephmccullough](https://wordpress.org/support/users/stephmccullough/) ,
 * I hope you’re doing well.
 * I would recommend checking Cloudflare, as threadi mentioned. I see that you commented
   that it was not in use, but you can confirm it by checking your NameServers: 
   [https://dnschecker.org/#NS/therangerdesk.com](https://dnschecker.org/#NS/therangerdesk.com)
 * Your domain points to the Cloudflare service, which is fine, as it gives you 
   some benefits such as caching and security on the DNS end, but it could still
   cause loopback issues; usually following their recommendations to enable Optimization
   for WordPress here helps – [https://developers.cloudflare.com/bots/troubleshooting/wordpress-loopback-issue/](https://developers.cloudflare.com/bots/troubleshooting/wordpress-loopback-issue/)
 * It’s possible that you need to reach your Domain admin to check this.
 * Best Regards,

 * I created a staging site and changed the theme, which didn’t help. Then I deactivated
   all plugins, and I still got the same error that my site can’t complete a loopback
   request. This is what t-p gave me in the loopback info to troubleshoot, but that
   did not help.
 * And I’ll repeat: I do not have any bots running on cloudflare. Nothing is running
   on there that says it is blocking anything recently, let alone hundreds of cron
   jobs on my site.
 * And if it is not my hosting provider then what difference would changing hosting
   providers make?

 * I also have this error? Could this help?
 * The REST API encountered an unexpected result
 * The REST API is one way that WordPress and other applications communicate with
   the server. For example, the block editor screen relies on the REST API to display
   and save your posts and pages.
 * When testing the REST API, an unexpected result was returned:
 * REST API Endpoint: [https://www.therangerdesk.com/staging/3510/wp-json/wp/v2/types/post?context=edit](https://www.therangerdesk.com/staging/3510/wp-json/wp/v2/types/post?context=edit)
   
   REST API Response: (403) Forbidden

 * Your staging is still running behind Cloudflare on your hosters servers. So either
   one of them could still be the cause. The fact that you’re getting a 403 error
   even with the REST API is a particularly strong indication of this to me. I would
   recommend trying the approach mentioned above again.

 * And I have this error: Your site is running on an older version of PHP (8.2.32)
   which should be updated. PHP is one of the programming languages used to build
   WordPress. Newer versions of PHP receive regular security updates and may increase
   your site’s performance. The minimum recommended version of PHP is 8.3.

 * You should also upgrade the PHP version, but that won’t solve the problem unless
   your hosting provider makes some fundamental changes.

 * I turned Cloudflare to DNS only (bypassing it completely) and still am getting
   the same errors. Cloudflare support is telling me that means it is my hosting
   provider. I will try to talk to them again. Last time I spoke to my hosting provider
   for hours and they couldn’t find anything wrong on their end.
 * Does anyone have any ideas what specifically I could ask them? Or if there’s 
   a way I could figure out what is wrong with the host myself? I can’t afford to
   switch my site to another hosting provider, as was suggested.

 * Also ask if they can update Curl — in case you are running an outdated version.

 * Hi [@stephmccullough](https://wordpress.org/support/users/stephmccullough/) ,
 * I hope you’re doing well.
 * From your hosting, I would check:
 * – Temporarily disable the Firewall (if possible)
 * – SSL Configuration issues – Poorly configured SSL certificates can also cause
   problems with loopback requests. Try reinstalling and reconfiguring the SSL certificate
   as a fix.
 * – Outdated Software – As t-p mentioned, verify all the Software on your system
   is up to date. Outdated software and libraries, including PHP, cURL, or OpenSSL,
   can also cause this issue.
 * – Limited Resources – Limited Server Resources, including the PHP memory limit
   and Maximum upload space can cause cURL request issues.
 * Apart from this, you could check if there is any server configuration that could
   be causing this, but this would be from your hosting Support end directly.
 * I hope this helps.
    Best Regards, Williams Valerio
