Problems with license

OS Name/Version: UBUNTU SERVER 22.04

Product Name/Version: AMP Release “Halimede” v2.4.0.10, built 27/10/2022 18:15
Problem Description:

every time I launch the AMP interface,
I have this message popping up.

AMP has lost its licence key due to a hardware or system configuration change.
Please re-enter your licence key under Configuration -> New Instance Defaults.
You may also need to reactivate your existing instances on this host.

How can I fix this problem?
Knowing that
AMP is installed on a dedicated machine,
No docker
only one ethernet interface with static MAC and fixed IP.

Steps to reproduce:

Can appear randomly when I refresh the page

Actions taken to resolve so far:
enter the license under Configuration → New instance and restart instances.

What’s the output of ip addr ?

here is the output,
would IPv6 be the problem?

~$ ip addr
1: lo: <LOOPBACK,UP,LOWER_UP> mtu 65536 qdisc noqueue state UNKNOWN group default qlen 1000
link/loopback 00:00:00:00:00:00 brd 00:00:00:00:00:00
inet scope host lo
valid_lft forever preferred_lft forever
inet6 ::1/128 scope host
valid_lft forever preferred_lft forever
2: enp0s31f6: <BROADCAST,MULTICAST,UP,LOWER_UP> mtu 1500 qdisc fq_codel state UP group default qlen 1000
link/ether 4c:cc:6a:d7:01:7c brd ff:ff:ff:ff:ff:ff

valid_lft 1788sec preferred_lft 1788sec
inet6 2a02:8428:469e:df01:1:2:3:12/64 scope global
valid_lft forever preferred_lft forever
inet6 fe80::4ecc:6aff:fed7:17c/64 scope link
valid_lft forever preferred_lft forever.

I can confirm that it’s happening, AMP having issues with remembering passwords or other things.
when rebooting a server this usually happens.
