    Hello, there.

    What are you trying to accomplish exactly, and what isn’t working the way you expect?

    If you’d be able to provide us with the steps you’re taking when you see this error and where exactly you’re seeing it, that would definitely help.

    One more thing before I send this reply back to you – It looks like your xmlrpc.php file (which is needed for Jetpack to work properly) is coming back as a 503 Service Unavailable error when we try to connect to it, and we’re also seeing some timeouts happening.

    In this case, I would recommend reaching out to your webhost to first make sure that Jetpack is not getting blocked or limited or is prevented from accessing your xmlrpc.php file. They can check their error and connection logs for these 503 errors to see exactly what is causing them and hopefully fix them for you.

    For the best results, you would also have them allowlist the Jetpack IP ranges noted on this page:

    https://jetpack.com/support/how-to-add-jetpack-ips-allowlist/

    Aside from telling us more about the error you posted in this thread, please do let us know once you’ve talked with your host as well so we know that Jetpack is connected and working properly before we continue to troubleshoot. Thanks!

    Thanks for the response.
    The error disappeared when I turned off “Bot” in Cloudflare.

    To prevent unauthorized access to xmlrpc.php, I blocked IP access to the file about a week ago in cloudflare and added the following Jetpack IPs to allowlist:

    While I’m glad that the error went away, it’s still unclear if it is related to Jetpack and why it went away.

    We’re still seeing the 503 error when we test your connection.

    I’d recommend following these steps to configure Jetpack to work with Cloudflare:

    https://jetpack.com/support/getting-started-with-jetpack/configure-jetpack-cloudflare/

    If the Jetpack connection still isn’t working, you will need to reach out to Cloudflare.

    Additionally, regarding the initial error message, can you share what you were trying to do at the time you encountered the error? That would help us to reproduce it.
