AuthenticationService.Authenticate error

Hi,
I am having problems with your plugin. When fetching a page with your map on it via Goolge Webmaster Console, the page is labeled as “partially” available.
The following linked gets blocked:

I would be very thankful for your assistance in with this matter.
Best regards,
