Unable to obtain Let's Encrypt SSL Cert for domain where Cloudflare provides authoritative nameserver services. Neither did CyberPanel create a self-signed cert as docs stated would happen if certbot failed. Error message: 283 Failed to obtain SSL for domain. [issueSSLForDomain] 
Certbot seems to do fine with cPanel brand hosted websites running LSWS Enterprise under same circumstances so suspect this is fixable.
