Hello,
I have try to resolve this issue last two days. How to resolve this issue? how to contact technical person? how to resolve easily? becuase i only update the cname record then after try to verify but issue is cloudflare banned the cname on the sub-domain. Try to connect with gitbook. please resolve this issue. My site is only document. please resolve as soon as possible.
Additionally, an error 1014 can be returned when a Cloudflare Apps is used on a client domain which origin is a provider using our SSL for SaaS solution. Unfortunately, this set up is not yet supported.
Resolution
To allow CNAME record resolution to a domain in a different Cloudflare account, the domain owner of the CNAME target must contact Cloudflare Support and specify the domains allowed to CNAME to their target domain. A Cloudflare Pro, Business, or Enterprise plan is required on the target domain for Cloudflare Support to change default CNAME restrictions.
I have configure my subdomain with gitbook.io. gitbook.io his using to Cloudflare. i have try to multiple times reconfigurations but same error after some days. i request to please allow to cname. i not declare to sub-domain for security reason.
