Google maps API key that was working earlier is not working now?

For a form of mine, I had google maps enabled that was working fine for sometime but there seems to be an issue now with it. Have not changed anything in the form.

This form has been duplicated for various purposes and the same issue persists in all forms

Please try getting a new API key and let us know if the issues still persist.

Also, I cleared your form cache on our server. 

Give it a try and let us know if you need further help.
