Got an out of the blue error on the main virtualmin page about dnssec expiring which shouldn’t be as it’s set to resign itself like normal. Tried manually and got the following error:
Failed to re-sign zone : Re-signing failed : dnssec-signzone: warning: /var/lib/bind/mydomain.hosts:57: signature has expired dnssec-signzone: fatal: Zone contains NSEC records. Use -u to update to NSEC3.
Operating system Ubuntu Linux 20.04.4
Webmin version 1.990
Usermin version 1.834
BIND version 9.16
Appears it wants something upgraded related to either Bind or DNSSEC but as the panel function is controlled by virtualmin/wemin not sure what to do here.
