Hi,
I’m trying to use the NameServer setup during Hestia installation (ns1.mydomain.xyz and ns2.mydomain.xyz).
I have attempted to point my domain name to my Hestia Name Servers, My domain name registrar says the nameservers are not valid.
What did I miss?
Did you created a name server cluster? https://docs.hestiacp.com/admin_docs/server_management.html#how-to-setup-a-dns-cluster
No I didn’t.
Should I run the command on the same server that Hestia is running on?
If you want to get a dns cluster, you probaly should 
. But you need to know what you’re doing, also have a propper plan for the cluster - otherwise it would be a good idea to stay on cloudflare or a similar service.
You should create a child nameserver from your name registar example if your using namecheap on advance dns
Register personal dns server then point your ns1,ns2 to your ip
But Personally i use cloudflare , easy to use you can just change the ip , MX and your site will be back online if you transfer to other provider
