Connection lost

wp-admin/admin.php?page=jetpack-debugger: Bitácora Almendrón is not connected.: 200. Reconnect Jetpack now.

I reconnect but;
Here was an error reconnecting Jetpack. Error: The Jetpack server was unable to communicate with your site https://www.almendron.com/blog/ [HTTP 202]. Ask your web host if they allow connections from WordPress.com. If you need further assistance, contact Jetpack Support: http://jetpack.com/support/

I have deactivated all plugins except JetPack, but the error persists.

All three sites show the same problem:
