my dns do not resolve

Good morning after having problems with the domain registrar and register another domain with another registrar, the domain isservidoresargentinos.com and configure ns1.servidoresargentinos.com and ns2.servidoresargentinos.com to the ip that my VPS provider told me to is the main ip of the cwp.
The ns do not solve I am needing some help if it can be.
Thanks

There is nothing much we can do if the DNS server belongs to the registrar. The mentioned domains does not resolve to anything, so you should contact whoever is responsible for the DNS server.

Contact your registar, and tell them you need Glue Records for your domain to point to your server.  They will know what to do from there if they are worth anything.
