I’m trying to implement CloudFlare in my domain. In the update Registrar step, when I try to replace with Cloudflare’s nameservers, my Registrar in Brazil (Registro.br) show me the error “Pesquisa Recusada” = “Search Refused”
In CloudFlare Startup Wizard. I Create the domain, CloudFLare show me the current entries on my DNS and when I click in continue, the CloudFlare guided me to replace my current Servers with CloudFlare Name Servers. I attach the image of this screen:
In that case it might be the same issue at Org.br not accepting Cloudflare nameservers and I would also suggest to contact support. They should be able to clarify what the issue is.
