Could not connect to wordpress.com

Hi,

I had to deactivate the jetpack plugin for some reason. It was working quite well before that. But when I tried to activate again it could not connect to my account. It shows this error:

Jetpack could not contact WordPress.com: register_http_request_failed. This usually means something is incorrectly configured on your web host.
Operation timed out after 15001 milliseconds with 0 bytes received

I deleted the plugin and reinstalled again but the result was same.
