It seems Google is hosting your site and your SSL certificate has expired. Likely using the Cloudflare proxy for www is blocking the certificate being re-issued.
* Server certificate:
* subject: CN=www.shopmedicalz.com
* start date: Mar 26 15:07:39 2024 GMT
* expire date: Jun 24 15:07:38 2024 GMT
* issuer: C=US; O=Let's Encrypt; CN=R3
* SSL certificate verify result: unable to get local issuer certificate (20), continuing anyway.
shopmedicalz.com is unproxied and the IP address that (on http) returns belongs to Google - maybe your host uses Google. That then redirects to www which is proxied and then a Cloudflare WAF rule blocks me from going any further. https://cf.sjr.org.uk/tools/check?1af3432bbb784c80940435e03140c072#dns
