1014 CNAME Cross User Banned

When you experience the 1014 CNAME Cross User Banned error, it's most likely because the domain you are requesting is set up with DNS records pointing to the Accelerated Domains endpoints, but the domain(hostname) is not set up in Accelerated Domains.

This is easily solved by provisioning the hostname in Accelerated Domains. As the domain is already pointing to Accelerated Domains, SSL validation can be done using HTTP validation. Ownership validation must still be done using DNS records if the hostname is not on Cloudflare and not part of Servebolts Cloudflare offering.

How to provision Accelerated Domains#

For now, it's only Servebolt support that can provision Accelerated Domains.

The error page you will be served#

The error page is served from Cloudflare due to how Accelerated Domains is built on top of Cloudflare.
