register_http_request_failed

I had connected Jetpack. But I disconnect to maintain my blog. After that, i re-connect, it error: Jetpact not contact WordPress.com ‘register_http_request_failed’

Please help me,

Thanks,

Could you both 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!
