Hi everyone,
My problem is fixed.
And my Squid server up to date (Ubuntu 22.04 LTS).
Finaly my problem was not about squid but about DNS.
Ubuntu could'nt find any more my AD server.
Solution :
Modify 2 files :
/etc/resolvconf/resolv.conf.d/head
/etc/resolv.conf
And put in it this line :
nameserver <ip of my AD/DNS server>
After serveral reboot/restart, the configuration is always in use.
Thanks for the help
Regards

Hi,
Here is the content of my actual /etc/resolv.conf (ubuntu 20.04) :
------------------------------------------------------------------------------------------------
# Dynamic resolv.conf(5) file for glibc resolver(3) generated by
resolvconf(8)
# DO NOT EDIT THIS FILE BY HAND -- YOUR CHANGES WILL BE OVERWRITTEN
# 127.0.0.53 is the systemd-resolved stub resolver.
# run "systemd-resolve --status" to see details about the actual
nameservers.
nameserver 172.20.0.1
nameserver 127.0.0.53
search stemarie-aizenay.local

Bruno, thanks for the suggestions.
I will try after Christmas Hollidays.

It could be something related to default systemd dns services.

Yep, I had the same issues when I upgraded from 4 to 5, because I
also upgraded the distro version along with it, and systemd-resolved
is enabled by default in some, such as Fedora and Ubuntu. It stopped
resolving local domain names for some reason.
Instead of struggling to make it work on the new model, I simply
disabled systemd-resolved and went back to old resolv.conf style.
I'll quote the solution I followed here:
https://askubuntu.com/questions/907246/how-to-disable-systemd-resolved-in-ubuntu
====
This method works on the Ubuntu releases 17.04 (Zesty), 17.10
(Artful), 18.04 (Bionic), 18.10 (Cosmic), 19.04 (Disco) and 20.04
(Focal):
Disable and stop the systemd-resolved service:
sudo systemctl disable systemd-resolved
sudo systemctl stop systemd-resolved
Then put the following line in the [main] section of your
/etc/NetworkManager/NetworkManager.conf:
dns=default
Delete the symlink /etc/resolv.conf
rm /etc/resolv.conf
Restart NetworkManager
sudo systemctl restart NetworkManager
Also be aware that disabling systemd-resolvd might break name
resolution in VPN for some users. See this bug on launchpad (Thanks,
Vincent).
