Bigin Form with reCAPTCHA not working

I created a form in Bigin and added Google's reCAPTCHA and all looks good until I insert it into my webpage. I have added both my domain and the crm.zohopublic.com domain to the reCAPTCHA domain settings, but on my webpage it gives the following error:

ERROR for site owner:
Invalid domain for site key

If I uncheck the verify origin option, it shows fine, but when enabled I get the error. I am not sure what other domain it would be expecting. The site is hosted via Wix. And yes, I've added wix.com and variations to try to get it to work. If anyone has any insights, I would greatly appreciate them.
