Zoho CRM for Google is not responding

Zoho CRM for Google is not responding

When I click Authenticate Google Contacts it takes me to the Google acceptance page as it should.  However, once I click accept, I do not get the Sync Contact / Sync Options page, but rather I am returned to the Authenticate Google Contacts page.  Help please?  Is there an issue in Zoho that is causing this?  Thanks.
