DNS between a Virtualmin master and a Webmin slave operation cancelled error

Nov 16 04:44:48 23 named[13751]: zone seanieb.com/IN: refresh: failure trying master 68.71.25.202#53 (source 0.0.0.0#0): operation canceled

I get this whenever I reload the zone on my Webmin server syncing from a Virtualmin server.

the Zones were synced with Cluster DNS Slaves, it made the zones, but no records.

Both machines run Debian, apparently with the same BIND version.

Do you get any errors in the syslog on the master server? Is BIND listening on TCP port 53 for external addresses? Is a firewall blocking incoming TCP traffic on port 53 for the master?

The text of the error I posted was from the syslog of the slave. The master does not output anything.

Master to Slave:

Okay, seems the systems can reach each other fine.

Please check the syslog of the master server too, if any errors are recorded there.

Also check the BIND module in Webmin, section Zone defaults, if there's any entry in "Allow transfers from", and if so, if it's the right IP. The same you can do for the respective zone, section Zone options.
