hello
I update WP 3.7 and have some problems so I deactivate all plugins to find the problematic one… after find it… I activate jetpack again but wen I try to conect to wordpress.com I recibe this error.

Jetpack no pudo ponerse en contacto con WordPress.com: register_http_request_failed. Esto generalmente significa que algo no está configurado correctamente en su alojamiento web.
