Your website needs to be publicly accessible to use Jetpack: site_inaccessible Error

Below error occurred while trying to connect to the WordPress.com under jetpack plugin in wp-admin panel:

Your website needs to be publicly accessible to use Jetpack: site_inaccessible Error Details: The Jetpack server was unable to communicate with your site [HTTP 503]. Ask your web host if they allow connections from WordPress.com. If you need further assistance, contact Jetpack Support: http://jetpack.me/support/

Try disabling the maintenance plugins if you have enabled and try to connect it.

The maintenance plugins like : WP Maintenance Mode and ThemeFuse Maintenance Mode

Or try disabling all the plugins that you have recently added and try if it is getting connected.

Or try deactivating the Jetpack plugin and reactivate it again and try connecting it , this worked for me .

Also check if your domain name server is updated , or updated to the right hosting account. Also check if the A record is pointing correctly.

If this is not resolved the issue you will have to contact either the http://jetpack.me/support/ or the hosting provider to check if the port is blocked or the website is blocked.
