reCaptcha Problem

Hello everyone,
I’ve been using my sub-domain to design and test a clients website. reCaptcha was working fine on my sub-domain. This morning we made the website live by pointing my cleints “A” record to my Hosting provider “his name servers are with GoDaddy”, and loading his files to his domain directory on my servers. The issue I’m having is now when I submit the form on his new site, I’m getting a “reCaptcha connection failed” error message. The reCaptcha box shows up properly and I have the clients domain listed on the Google reCaptcha account. Anyone have any Idea’s why it might be doing this?

I’m jus trying to figure out why reCAPTCHA would show on the page properly but when I submit the form it gives me the error message “Captcha connection fail”
