1) check your laptop is configured to work with this DNS server (cat
/etc/resolv.conf on laptop or "ipconfig /all | findstr DNS" in case of
windows )
2) check server is accessible (ping <YOUR_SERVER_IP> from laptop)
3) check server is accessible via TCP/53 ("telnet <YOUR_SERVER_IP> 53" from
your laptop)
4) check firewall on server and/or devices between server and laptop, it
may block requests
5) check your server is configured to use the same DNS: cat
/etc/resolv.conf
