[Pdns-users] PowerDNS suddenly refuses to resolve

Hi all,

One of my pdns name servers has suddenly stopped resolving, giving a
status to dig of status: REFUSED. I have no idea why as it was working
perfectly well for several days (it's a new installation).

My other nameserver, which is a renamed clone of this one, continues to
work perfectly well. Thankfully!

I'm using PowerDNS 4.2.1-1build2, on Ubuntu Server 20.04, on a Digital
Ocean VPS. Firewalling is not an issue as port 53 is open. I have the
tinydns backend enabled as I migrated from DJBdns, and haven't had time
to get an sql file sorted out for import.

Here's the dig result in full:

dig convergent-ict.com NS @ns6.convergent-ict.com

; <<>> DiG 9.16.1-Ubuntu <<>> convergent-ict.com NS @ns6.convergent-ict.com
;; global options: +cmd
;; Got answer:

;convergent-ict.com.		IN	NS

Obviously the errant server is ns6.convergent-ict.com, and for
completeness, the one that's working is ns7.convergent-ict.com

Thanks in advance for any help.

Cheers, Laurie.
