Hello,
I don't why DSState: hidden, it's ok with some online check tools like :
- https://dnssec-analyzer.verisignlabs.com/
- https://zonemaster.net/fr/run-test
my master is hidden, it can be related ? How i can debug this DSState:
hidden ?
I found this command to check actual status : rndc dnssec -status **********
This is the output :
....
key: 46358 (ECDSAP256SHA256), KSK
published: yes - since Tue Jan 17 17:55:03 2023
key signing: yes - since Tue Jan 17 17:55:03 2023
Next rollover scheduled on Tue Jan 24 17:55:03 2023
- goal: omnipresent
- dnskey: omnipresent
- ds: hidden
- key rrsig: omnipresent
...
Regards Adrien
