I checked your site, but I was not presented with any verification box, not even when I used a VPN.
Can you provide a screenshot of this verification pup-up you’re seeing? I suspect this may be coming from elsewhere, perhaps Google’s ReCaptcha service.
Also, note that your domain is notcurrently Proxied, requests not going through Cloudflare’s Proxy and Cloudflare’s WAF can’t be working for your domain.
