Unbound cache DNS server which is working fine but today I found that it fails to resolve certain domain name which is perfectly resolve by google DNS server.
According to my knowledge possibilities could be,
Nameserverof that domain blocking us?
- I was denying some domains due to DNS attacks, and is this one of them?
- Network issue?
I'm very new to
Unbound and like to find out how can I troubleshoot these cases.
Any help appreciate!
