Best Answer
The error tells you - you have no A records for your name servers. This means you are probably hosting your own primary and secondary name servers, so you'll need glue records as well.
In your zone file, you need to add something like
and then check the zonefile with
named-checkzone ringochat.com /path/to/zonefileIf it reports loading OK (with maybe a "out of zone info ignored" for your glue record servers) then edit again, increase your serial, and restart bind.
