Google Docs for Jetpack Connected WordPress website

Hello!
Added WordPress.com for Google docs add-on. Followed normal steps and when asked to add site got this error: That site does not seem to be accessible or no longer has the Jetpack plugin installed.

I use Cloudflare,i had debug follow this: https://jetpack.com/support/getting-started-with-jetpack/configure-jetpack-cloudflare/ ,but it not working.

I do not use the classic editor plugin, and I had deactivated all other plugins except jetpack, but the problem remains.

Checked the site’s speed and SSL certificate grade and found no issues.
Tested xmlrpc.php file and passed both checks.

Any suggestions for resolving the issue.
