benfitita 10 Posted ... I've noticed I have a problem with resolving kolabnow.com domain from my router. My router has unbound (DNS Resolver) running configured to forward queries to 10.4.0.1. Generally DNS resolution works fine, except for kolabnow.com. I think it's some kind of a problem with my setup, take a look below at this SSH session on router. Everything's fine when resolving example.com and other domains: dig @localhost example.com ; <<>> DiG 9.14.12 <<>> @localhost example.com ; (2 servers found) ;; global options: +cmd ;; Got answer: ;; ->>HEADER<<- opcode: QUERY, status: NOERROR, id: 19292 ;; flags: qr rd ra ad; QUERY: 1, ANSWER: 1, AUTHORITY: 0, ADDITIONAL: 1 ;; OPT PSEUDOSECTION: ; EDNS: version: 0, flags:; udp: 4096 ;; QUESTION SECTION: ;example.com.

I'm getting SERVFAIL on kolabnow.com.

Does it mean kolabnow.com NS is misconfigured? Can I change any unbound settings to workaround this? Quote Share this post Link to post
