samba - Sep 2023 - dnsupdate_nameupdate_done: Failed DNS update with exit code 110

Hello,

i have a fresh installed Member DC with Samba 4.17.10. Kerberos and 
internal DNS ist working. But i have trouble to update the Reverse Zone. 
When i restart the samba process then i have following log entries:

With "samba_dnsupdate --verbose":

The funny thing is, that with "samba_dnsupdate --verbose 
--use-samba-tool" the dnsupdate works. What is the Problem?
