Jetpack seems to be seeing everyone visiting your site as the same IP. Probably a mis-configured reverse proxy on the server, but we have a way around that.
I made that change on our end, and it will take about 5 minutes to take effect. Please let us know how it is after that!

As for not receiving the email, it sounds like your hosting provider has disabled PHP’s mail() function, which is used by WordPress to send you email notifications, and is also used by contact form plugins and more.
This is a common safeguard employed by hosting providers when they suspect that another customer on the same server is sending spam emails directly from the server.
Another alternative is that PHP’s mail() function is still active, but spammer activity from the server has already caused any email sent from it to be blacklisted. This would result in the emails being sent, but never received by any email address with basic anti-spam capabilities.
You can check this by leaving a comment on your site and checking if you receive an email. Another alternative would be to use the Health Check plugin and sending yourself a test email from the plugin’s Tools tab to see if it works.
If you didn’t receive a test email, you could try using an SMTP plugin to configure your WordPress site to use your email’s outgoing mail server instead of PHP’s mail() function.
Thanks for the reply. Regarding the mail problem, it was identified as host problem. They rectified it.
But I don’t understand the cause of misconfigured reverse proxy. Is it misconfigured from cloudflare or from host side?
It would be helpful to pinpoint the cause for future safety to not locked of my site again in future. Also, I got into my site by deactivating the cloudflare to get past jetpack locked out issue. And then again activating cloudflare.
It’s a misconfiguration on the server’s side, but we can get around that by literally just checking a box in your site’s configuration on our end. 🙂
Nah! It bugs me again. I am using jetpack with cloudflare since past 2 years without issues. But this issue is frustrating. Pausing the cloudflare and wait for a minute, I don’t get any locked message. No change in server dns. However installed mailpoet plugin recently. Does it interfere with jetpack?
After some testing, My observation is that jetpack is conflicting with the WP Rocket plugin Cloudflare add on option. I turned it off and no jetpack error till now. I hope it helps jetpack as well.
