I'm having difficulties trying to open the admin control panel (https://mail.testzserver.com:7070) as I'm getting an error that the page is not available. Basically, I have already set up all the required settings and configurations. Helpful info: My Zimbra server IP: 192.168.3.226 My Gateway IP: 192.168.0.32 DNS nameservers: 8.8.8.8 My configurations: /etc/resolv.conf /var/named/chroot/etc/named.conf /var/named/chroot/var/named/db.testzserver.com When I do nslookup testzserver.com, I get this error in line: **server can't find testzserver.com: NXDOMAIN What should I have done more? Thanks in advance!
