The problem is this site - http://www.registro.br that does not recognize the DNS of WordPress. The site said the DNS server is refusing to send the domain information to its system.
Registro.br says: the DNS domain server must be previously configured for the domain you want then you can register your domain with .br
Where can I configure this in the WordPress if it accept this operation just after registering the domain?
The blog I need help with is computacaojatai.wordpress.com.
