Why can’t I change my .hu domain’s nameservers?

In most cases the source of the problem is that you can’t change your name servers as long as your nameservers aren’t qualified as valid nameservers. This qualification is done by the .hu Registry, you can test your nameserver with the given domain at this link:
.hu domain nameserver technical checking

(You can’t change your domain’s nameservers on our technical interface/panel either as long as the given site’s tool gives you errors)

You can read up and learn how to fix the issues with your nameservers, or we can give you and set up a free CPanelDNS service (which is a qualified nameserver) if you want. You can change your nameserver any time for free (as long as it passes the tests on the given link)
