I have a problem.
At my VPS I have 3 IP's one for the main server and 2 for NS.
After I have created NS1 and NS2 I wanted to test the NS at isnic.is but I get this error.
Test result # CHK-20191120.195322 for ns1.domain.is:
The nameserver NS1.DOMAIN.IS (126.96.36.199) seems to ignore test queries to UDP port 53
The nameserver NS1.DOMAIN.IS (188.8.131.52) seems to reject connections to TCP port 53
All ports are open.
Any Idea why this is happening.
