Google reCAPTCHA isn't working consistently. Was working in the past, now validates intermittently.
To be more specific, the reCaptcha field appears as expected on page load as seen below:

However, on click, the validation hangs, as seen below:

This is the response from the logs:

(This says "Failed to load resource: the server responded with a status of 400() )
This issue surfaces on: Chrome, Safari, Firefox, and IE (with it less common on Firefox and IE).
However, occasionally, the error is not present and the validation works as expected, as seen below:

This would lead me to believe there is potentially an overload on Google's server, but I'm not sure and thus reaching out for assistance and any guidance that may be available. Thanks in advance for your time and help!
