![]() The nameservers will return a REFUSED answer and the recursive resolver is generating that SERVFAIL you're seeing.Ĭonfigure the domain to use the name servers assigned to the hosted zone on its creation. You're getting a SERVFAIL because you're sending DNS queries to a name server that is not authoritative for that domain (those NS are probably from a deleted hosted zone). Those are the ones you must configure in your domain if you want it to resolve to the DNS records created on the HZ. Those are the ones associated to the hosted zones, the ones that will answer for the records created there. Like if I put in nf, but then dont have an zone where the zones should be.

The name server on the SOA is not any of the name servers on the NS, that probably implies that the name servers for that hosted zones are not the ones on the NS. value: the rcode value: int string """ text = _by_value. isdigit ( ) : v = int ( text ) if v > = 0 and v 4095 int """ value = ( flags & 0x000f ) | ( ( ednsflags > 20 ) & 0xff0 ) if value 4095 : raise ValueError ( ' rcode must be >= (int, int) tuple """ if value 4095 : raise ValueError ( ' rcode must be >= 0 and <= 4095 ' ) v = value & 0xf ev = long ( value & 0xff0 ) << 20 return ( v, ev ) def to_text ( value ) : """ Convert rcode into text. text: the texual rcode text: string UnknownRcode: the rcode is unknown int """ if text.
