Hello,
That would be an issue with your ssl cert, it is most likely viewing the calls to google's servers as external content and blocking it since it's not called from your domain. The extension itself cannot change that, it's all controlled through your ssl cert. Your host may be able to set it to allow specific external content.
I reissued a key from the Google API manager, and also removed the limitation that only allowed access from my domain. This does explain what was going on, since if I want to re-implement the limitation, I may need to add my SSL issuer's domain as well.
It's working great now. Thanks for the help!
