DNS Error, rcode=REFUSED

I’m confused by the errors I’m getting. I just created a new Ubuntu 22 box and installed v60 of mail-in-a-box. I’m pretty sure I setup glue records correctly on namecheap, but the admin page says:

Nameserver glue records are incorrect. The ns1.box.mydomain.com and ns2.box.mydomain.com nameservers must be configured at your domain name registrar as having the IP address (myIp). They currently report addresses of [Not Set]/[Not Set]. It may take several hours for public DNS to update after a change.

Running the command

$ dig @ box.mydomain.com

Gives errors “No Reachable Authority” and “Network Error rcode=REFUSED”

Could DNSSec be causing this? I disabled it about an hour ago.


You may need to wait up to 24 hours for DNSSEC to become totally disabled.
