Hi @advgyan –
In order for Jetpack’s CDN to work, we need to have a working connection between your website and Jetpack. Right now, that connection is not working.
As a first step here, would you please delete Jetpack and then reinstall it? This should cycle the connection. You can follow these steps to do that:
1. Start at Plugins → Installed Plugins.
2. If Jetpack is currently active, click Deactivate to disable it. Then click Delete to remove it from your site:
3. Go to Plugins? → Add New.
4. Search for “Jetpack by WordPress.com”.
5. Click Install and then Activate.
When Jetpack is installed, click the green Set up Jetpack button to reconnect.
This handy guide explains that process in more detail:

You shouldn’t lose any settings or any of your stats or subscribers in doing so, as that info is stored in our system here.
Please let us know once you have done that and we can check your site’s connection.
