Works locally, not on staging server

[hyperflux]

Locally, recaptcha loads and quickly verifies with the green check mark after clicking. When I move to my staging server, it loads but after clicking the blue circle spins and javascript error returned is "Uncaught (in promise) Timeout (f)".

Any ideas why this isn't working on my staging server? Yes, I have added the staging server domain to the list of domains on Google's recaptcha configuration site.

Same problem here... Any solution?
