The Jetpack server was unable to communicate with your site [HTTP 404]. Ask your web host if they allow connections from WordPress.com. If you need further assistance, contact Jetpack Support: http://jetpack.me/support/

Answer 1

I had this issue because I have installed iThemes Security plug-in. To solve the problem :

1. Disable it.

2. Connect JetPack

3. Enable it and look what exactly in the config is making the problem.

   Probably other security plug-ins/firewalls will have the same effect.
