cups-pki-invalid error on CUPS 2.3.3op2 on RaspberryOS

[Rallyefahrer]

Hi,

After a fresh installation of RaspberryOS Bullseye 64bit and CUPS 2.3.3op2 as print server, using brlaser v6 driver
(status Idle, Accepting Jobs, Shared, Server Default) any printing attempt from network will abort always with the error "cups-pki-invalid".
Error message in /var/log/cups/error_log: [Client 50] Unable to encrypt connection: Error in the push function.

Same setup worked flawless in the past on this RPi.

Regards, Markus
