Hello,
I’ve a bug with one specific domain (new tld): .bnpparibas
I can’t resolve mabanque.bnpparibas if dns forwarding is activated (via foris checkbox)
And if I query directly the server I’m suposed to forward to, it works
Best than a long explaination :

Asking directly DNS server works

EDIT :
with or without DNSSEC support does not change the situation – WRONG
DNSSEC is the problem with this tld
Any clue on that problem ?
Thank you very much
PS: as for now, dns forwarding is disabled, but resolution takes muccccchhh longer
