No se pudo activar Cloudflare para tu web. Cloudflare is already activated for this domain under a different account

Cuando intento activar con siteground la opción de DNS me sale este error y no me deja activarlo.

¿Alguna idea de lo que ocurre? En cloudflare me estan dando largas y en siteground dicen que es problema de cloudflare

You may have to ask Siteground for help on this, but you can also open a ticket here.
