Nameserver issues

Hello guys,

Before, I've used an invalid second IP for my ns2 nameserver

After updating my nameservers in CWP, the DNS is still invalid and when I check my domain using leafdns.com
http://leafdns.com/
y0us3f.com <--

it still shows my old ip for ns2

and it's been almost 48 hours, still nothing updated.

please let me know how to fix this.
Thank you.

Fixed. Updated.
But leafdns.com still says that second IP for ns2 has a problem?

you need to attach the second Ip to cwp server ask your server provider
