Problem with own DNS and hostnames in VM instance

[MoorBe]

Hi, I created a VM instance and there I installed WHM to handle the server. It worked perfectly. Now I want to configure my own DNS and for this I created the host names in my domain that I have in Godaddy and I pointed them to the external IP that I see in the instance that I also configured as a static IP.

After doing this, any account that creates in the WHM simply doesn't work, I did this configuration more than 48 hours ago and it doesn't work. I don't know if I should do something else in the instance or if I should point the DNS from my Godaddy domain to an IP that I'm not seeing inside my instance.

The domain I'm configuring is moorbe.co and my own hostnames are ns1.moorbe.co and ns2.moorbe.co, both pointing to the external IP of the instance.

I wish that somebody here can help me with this situation.

Thanks!

If anyone has this same problem I was able to solve it, the problem is port 53 and it must be configured in the GCP firewall. By doing this everything worked perfectly.
