Jetpack's statistics stopped working yesterday (times out), so I tried deactivating the plugin and then reactivating.
Now I get this message when I try to connect Jetpack to WordPress.com
Jetpack could not contact WordPress.com: register_http_request_failed. This usually means something is incorrectly configured on your web host. SSL connection timeout
Host is fatcow.com, and this was working fine a couple of days ago.
