Servidores de nombres no válidos

What is the name of the domain?

sklable.es

What is the issue you’re encountering

Tengo 2 dominios en IONOS y configurados en Cloudflare, en ambos hice el mismo procedimiento de cambiar DNS en el proveedor. El primero funciona perfectamente, pero el segundo me indica " Servidores de nombres no válidos".He comprobado que las DNS se han propagado, y en mi proveedor si que aparecen las de Cloudflare tal y como las cambié, pero Cloudflare no lo detecta. Han pasado ya más de 48hs del cambio.

What feature, service or problem is this related to?

DNS not responding/updating

The 2 allocated Cloudflare nameservers are not set at the registry…

sklable.es.		86400	IN	NS	ns1087.ui-dns.de.
sklable.es.		86400	IN	NS	ns1074.ui-dns.org.

If you have set them at your registrar, then check with them as they are not set at the .es registry.

ahora deberían estar. Volví a empezar el proceso pero sigue el problema.

As I suggested, contact your registrar as the authoritive nameservers for your domain are ui-dns ones and the 2 Cloudflare nameservers are just NS records in your DNS which won’t work…

Contacto con mi registar y que es lo que debo decirle?

me dicen que se están propagando y que pueden tardar hasta 48hs.

The lookup I did is direct from the root servers so there’s no TTL.

It is however now set correctly and the domain is active on Cloudflare…

You will need to set the DNS records to point to your site, records for mail appear to be set already.

Works! thanks so much.

how can I add www DNS? what IP to point? I want to use workers and pages (for my landing) from cloudflare

@nikelodeum_services

I want to use workers and pages (for my landing) from cloudflare

In that case, you don’t need to enter an IP address (unless using a Worker route, in which case use proxied AAAA 100::). Just follow the developer guides for Pages/Workers to use a custom domain and that will create the required DNS records for you.
