    Hey everyone,

    We are dealing with WordPress websites not being able to loop back to them selfs: cURL error 28: Connection timed out after 10001 milliseconds

    https://developer.wordpress.org/reference/classes/wp_site_health/can_perform_loopback/#source

    Since it’s a cURL request, I’m wondering if I can reproduce the exact same things that the function of WordPress does, with just php + curl, and set full verbosity to be able to better troubleshoot what is happening or what is actually executed.

    It’s a struggle to troubleshoot it, without fully being able to understand what it does.

    The page I need help with: [log in to see the link]

    Please ask your hosting hosting provider why loopback don’t work on their server.

    Hello t-p,

    Thank you for your response, the problem is, that our customers are getting this error, I’m a representative of the hosting company asking the community for some help / guidance.

    There are several shackles in the chain, that could somewhere cause this, to pin point / research it, I want to know if it’s just one or a few backends that have this issue, or that all backends got the problem.

    I’m in the process if installing WordPress on a domain on each separate backend, login and check the health check, but this is tedious and manual labor.

    Ideally I would put a php file with the curl request on each backend and loop over them all and see which one(s) have this via e.g. bash / python, and save it’s full verbose information.

    Hopefully this helps explain the situation.
