The "No A, AAAA or CNAME record found" means that you don't have required entries in your DNS zone file at Cloudflare for the site to resolve properly. Please add the missing records to your zone file by going to: settings->DNS settings for the domain.
All sites generally have an A record that points to their server IP address. The record would look like:
A yourdomain.com (replace with your actual site name) points to server IP xxx.xxx.xxx.xxx (replace with your actual server IP address).
