The site on VDS is available only by IP. DNS purchased and configured. What is the problem?

Question

Domain Name System

Good afternoon,
a VDS was purchased, a Node.js server was raised on it, it listens at 0.0.0.0:80, the site is available and opens on the external IP 46.30.XX.XXX.
Bought DNS hosting from nic.ru. configured as shown in the screenshot. However, the domain name does not open the site: "Cannot find the DNS address of the server xxxxxx.com"
The server is running Ubuntu 14.04. Do I need to write something with resolvconf? If yes, what and where?

Thanks in advance.

Answer 1

You need to add the entry "@ A 46.****".
And then wait a while.
Now your server is available only on www.****.com
