** server can't find www.sangtawan88.com: SERVFAIL

[ANURAK.O]

Hi 

I am using google gateway server since publicdns can't find my ip web so I can't go online.
What can I do?

nslookup -type=a www.sangtawan88.com 8.8.8.8
Server:         8.8.8.8
Address:       8.8.8.8#53

** server can't find www.sangtawan88.com: SERVFAIL

i already check that domain can resoveled on my nameserver
but cannot resolve on publicdns

I am seeing that your domain is always being resolved successfully here. https://dns.google/ also shows a correct result from my end. From your earlier post, you also got a SERVFAIL with Cloudflare 1.1.1.1. So I think that's not the problem with our end specifically. Maybe you should contact the authoritative that hosts your domain.

One of your authoritative nameservers seems to be misconfigured returning servfail responses.

I suspect depending on which of the two servers has the lower latency to the google public dns instance you're querying your result will vary. At least thats how it would be with most recursive nameserver implementations.
