O problema mais óbvio é o PTR ou reverso do dns dos registros A para dois de seus servidores de Nomes que não resolvem nada ou não existe.
Verifique aqui - dnscheck do pingdom
Abaixo, você pode ver ns1.newage.design e ns2.newage.design são os culpados -
$for x in $(dig +short newage.design. ns); do echo -n "$x: " ; y=$(host $(dig +short $x) | awk '{print $NF}'); echo -n " $y : " ; dig +short $y ; echo;done ns3.newage.design.: toadshop.com. : 192.184.87.18 ns2.newage.design.: ns4.ktwebservers.net. : ns1.newage.design.: logix.aixair.org. :
privatesystems.net parece controlar a zona reversa do dns, direta ou indiretamente, você pode precisar contatá-los para corrigir o problema -
