If you are using your own nameservers,then:
- In your DNS you have NS1 and NS2 as A record that is pointing to IPv4 of your server
- NS1 and NS2 are registered as Nameservers at register of your domain.
If you are using other DNS,then:
- Double check if both www and non-www is pointing to your IPv4 - use https://mxtoolbox.com/DNSLookup.aspx for checking
- Remove AAAA records in DNS - use https://mxtoolbox.com/IPv6.aspx for checking (should return "DNS Record not found")
