named update signed zone got 'receive_secure_serial: not exact' error

xrise · Feb 17, 2022

As the title, I have a zone with :

Code:

zone "example.com"
{
   //...
   dnssec...  maintain;
   //
   inline-signing yes;
}

and I update the domain's IP with nsupdate:

Code:

zone example.com
update delete some.example.com
update add some.example.com new_ip
send

I get the error:

Code:

Feb 17 16:10:56 bsdrise named[2992]: zone example.com/IN (signed): receive_secure_serial: not exact

So, how to fix this problem?
