Regarding port 53 DNS

edited November 2019 in DNS Server

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 but I get this error.

Test result # CHK-20191120.195322 for
The nameserver NS1.DOMAIN.IS ( seems to ignore test queries to UDP port 53
The nameserver NS1.DOMAIN.IS ( seems to reject connections to TCP port 53

All ports are open.

Any Idea why this is happening.

Best regards
