I have a vps and seems like dns is not configured properly. host-tracker give me: Failure("Domain lookup failure:mydomain.com Exception:Not_found") In direct admin I have mydomain.com NS ns1.mydomain.com mydomain.com NS ns2.mydomain.com PHP: and in my domain registration panel I have added child nameservers pointed to my IP. What is wrong now?
Make sure you have a period at the end of your domain: mydomain.com. NS ns1.mydomain.com mydomain.com. NS ns2.mydomain.com Code (markup): You can also use a site like intodns.com to troubleshoot some of your issues: http://intodns.com
Are you trying to use an DNS server that is listed as an A record under the DNS record you are trying to setup? You used mydomain.com as both sites there- what are the real DNS settings?
You need to make sure you have set up host-records (child nameservers) at your domain registrar and pointed them to the IPs you wish to use for nameservers on the server itself. Without this step, this will likely fail.
