Cannot Validate Installation

I have installed and activated the HubSpot for WordPress plugin at: http://blog.stormpulse.com/

When attempting to VALIDATE YOUR INSTALLATION in on the Analytics Tracking Code and Privacy Settings page in the HubSpot Dashboard I get the following error:

We had a problem verifying your installation. Please try again.

Can you please let me know how to proceed?

Thank you,
