It's possible that cross-origin scripting between the client web application and Google is blocked by zone security.

Please ensure that both google.com and the webpage where the script is running fall into the same security zone (Internet Zone, typically.) If you aren't sure, see serverfault#612903 https://serverfault.com/questions/612903/ie11-how-to-check-into-which-zone-a-url-falls

Also ensure that the zone in which the web application and Google are classified is configured to allow script execution and ensure third-party cookie access is allowed for google.com as this is used to check for authorization.
