I had this error, "There was a problem loading this website. Try refreshing the page. If the site still doesn't load, please try again in a few minutes."
My site works but is still being controlled by Shopify's SSL for SaaS. It looks like instead of removing my domain from their services they just extended it or added custom rules. https://www.cloudflare.com/ssl-for-saas-providers/
Clicking the lock in the browser shows that it has a wildcard with sni.cloudflaressl.com
