For beginners: How to create a subdomain in vestacp?

Question

Domain Name System

Good day! There is a dedicated server for sprinthost, it has ubuntu, it has vesta, it has a domain. I want to create a subdomain for it. I create it: I add test.mydomain.market on the WEB tab, uncheck "dns support", go to the dns tab, find my mydomain.market, click in its corner to add an entry, write to test subdomains, enter the server ip address in ip, but subdomain does not start. chdnt?
dns of the main domain on hosting:
Name Server: ns2.sprinthost.ru
Name Server: ns1.sprinthost.ru
dns of the main domain for some reason looks like this:
SOA ns1.domain.tld

Thanks the issue is resolved. In addition to everything done, it was necessary to go to the control panel of the hosting provider providing boxing services and at the same time our domain registrar, and add an A record with a subdomain in the settings of the main domain.
