In Debian 12 the default /etc/ntpsec/ntp.conf file contains the lines

  # Comment this out if you have a refclock and want it to be able to discipline
  # the clock by itself (e.g. if the system is not connected to the network).
  tos minclock 4 minsane 3

which means ntpd needs at least 3 servers to choose from.  If you
haven't changed that line and you have only one server configured like
your output shows, you can never get synchronisation.
