Network Cameras not synching with Chrony HA addon

[0la1]

Problem/Motivation

I have two cameras in camera network (192.168.40.xxx) which are configured to get their time from chrony. They have firewall rules allowing to get into the HA network (192.168.20.xxx) on the Port 123. The cameras however does not update to a correct time. They are off by minutes and also by one hours (difference winter/summer time)

These are the Details.
Add-on version: 4.0.1
You are running the latest version of this add-on.
System: Home Assistant OS 13.1 (amd64 / generic-x86-64)
Home Assistant Core: 2024.9.3
Home Assistant Supervisor: 2024.09.1

Expected behavior

Cameras have the same time as HA.

Actual behavior

Camera times does not refelct HA time

Steps to reproduce

Set NTP Server on Camera to HA IP and Port 123
