CentOS 7 Problems / subdomain DNS failure: loading from master file failed: file not found

« on: March 28, 2021, 06:23:36 AM »

I use CWP7 as the web panel of my VPS. I just tried to add a new account with a domain like demo.example.com but it seems something is wrong with its DNS records.

When I want to add the domain to CentOSFreeDNSManager I face this error:

zone demo.example.com/IN: loading from master file /var/named/demo.example.com failed: file not found
zone demo.example.com/IN: not loaded due to errors.

here are the records I added to the CeonOSFreeDNSManager.


However, the /var/named/demo.example.com file exists.

Also, I checked the domain by this command:

named-checkzone demo.example.com /var/named/demo.example.com

and the result is:

zone demo.example.com/IN: loaded serial 2013071600
OK

I already did this many times and the subdomain worked without any extra kinds of stuff.

Here is the zone records of the subdomain generated by the CWP7 automaticly:
