vestacp open: /etc/named.conf: permission denied

This was the error I was getting after a doing a little change in the named.conf in my newly installed vesta control panel. While restarting the named, I was getting this error-

[root@vesta2 ~]# systemctl status named.service

Step-2: Setting permission-

chmod 644 /etc/named.conf
