GDPR issue with email newsletter form

I’m having issues with a email newsletter form in my footer. Everything was working fine but I changed the default domain and now people in the UK can’t submit their email. I’m using a GDPR cookie from finsweet and everything seems to be working but they’re still having issues submitting their email. I used finsweets visual debugger and everything came back normal. My form is connected to Mailchimp if that helps.
