Howdy,

Just to verify – it looks like your server is behind a NAT router… is port 53 UDP being forwarded from the router to your server?

If only port 53 TCP were being forwarded, that could cause the problem you’re experiencing.

Also, you may want to run “iptables -L -n” and verify that there isn’t a firewall blocking access. And the command “netstat -an | grep :53” will show what addresses BIND is listening on.

I run on a NAT router yes. Router Asus RT-AX68U. Went to “Wan” > Virtual Server / Port Forwaring, and opened the ports needed.

This is now fixed for now. I redid all the IP configuration and DNS configuration, and now it works!
