"IP has been flagged for potential security violations" but not my IP

Do you use a caching service or plugin on your site? If so, could you try to deactivate it?
If that doesn’t help, the issue is most likely caused by your server setup and the way queries are handled there.

If deactivating the caching service / plugin doesn’t help, can you please use Jetpack’s Debugger module to send us some more information about your site?

1) Go to the Jetpack page in your dashboard.
2) Click on the Debug link appearing at the bottom of the page.
3) Click the link that says “click here to contact Jetpack support.”
4) Fill in the description box and your name and email address.
5) Click the “Contact Support” button.

Thanks!

Thanks for support jeremy :)this is a great plugins ??

So how was it resolved? I have the same problem.

@joneall Could you try to follow the steps I posted above?

Thanks!

I have the same issue that just started today. I can not access WP-ADMIN to implement any fixes. How do I regain access to my site? I never have had this issue before and I dont understand why it just started. Please help.

Also, I have tried multiple IP’s and every single one is blocked. I have tried my 4G mobile network and rest my connection multiple times to gain new IP’s but all are blocked.

Disregard my messages. I had my hosting company disable jetpack and I gained access. Even my hosting company’s IP was blocked. I had friends all over the world try and log in and EVERY IP was blocked! How can this happen?????

That’s most likely because of a configuration issue on your server; regardless of where you’re connecting from, your server always logs its own IP address instead of logging the visitor’s IP. As a result, once that server’s IP address got blocked, everyone got blocked since that IP was logged for every attempt.

That’s something that can be fixed by your hosting provider, or we can work around it by tweaking your site’s Jetpack settings. If you’d like to give Jetpack another try, can you please use Jetpack’s Debugger module to send us some more information about your site, so we can make the necessary changes?

1) Go to the Jetpack page in your dashboard.
2) Click on the Debug link appearing at the bottom of the page.
3) Click the link that says “click here to contact Jetpack support.”
4) Fill in the description box and your name and email address.
5) Click the “Contact Support” button to send us the debug results privately. It’s best not to post this information on public forums, as it contains private details about your site.

Thanks!
