What if I change the name server, but it fails and the reason is [information change failure (empty non-extended update is not allowed)] ?

This is a case where an attempt is made to change the already changed name server again.

If you check the WHOIS information and confirm that the name server has changed, you do not need to retry. Please wait as the reflection time for name server changes is approximately 24 hours.
