Amazing, thanks for sharing the URL ??
I see a different error when running a diagnostic test on your Jetpack connection. I get the following error: “cURL error 28: Operation timed out after 5000 milliseconds with 0 bytes received”.
This usually means that your web host is blocking some connections Jetpack needs in order to work correctly.
Could you please contact your web host and ask them to make sure that the connections to and from *.wordpress.com are whitelisted?? In terms of IP ranges, the following ranges need to be fully whitelisted:
185.64.140.0/22
2a04:fa80::/29
Also, all of the IPs listed here:
https://whois.arin.net/rest/org/AUTOM-93/nets.
Let me know what you find out!
