Title:
Avahi-daemon withdraws address record
I've just seen this issue the first time on a Ubuntu 20.04 (updated
several months ago from 16.04) AWS EC2 machine. Looking closer into
this, the machine lost its IP address multiple times in the last hours.
The following avahi-daemon log messages made me find this bug report:

Raspberry Pi OS (stock kernel).

Are you guys sure it isn't Avahi? It was still happening to me after
stopping the network manager service. Is it not the incompatibility
mentioned in the Arch docs? https://wiki.archlinux.org/index.php/Avahi
My ip and dns finally stopped changing when I disabled Avahi. Also

I am also seeing this same problem on a Raspberry Pi4 4GB.

The Pi was rock solid and did not exhibit any problems until 2020-02-24

The bug was marked invalid for *Avahi* but Confirmed for network-manager
-- because the bug exists not in Avahi (it simply logs the message you
see as a result of the IP address being removed). So the bug is still
valid and confirmed, just for network-manager instead.

I found a workaround this problem.
Check my git

If the IP is not found then 'dhclient' will be called on that given
interface(card)
This is happening on 16.0.4 LTS with ethernet connected PCs. Relevant

I think I found the culprit:
https://bugs.isc.org/Public/Bug/Display.html?id=45540
It boils down to a bug in the isc-dhcp-client. It doesn't correctly
react to time synchronization events and therefore simply breaks in
situations where time jumps "backwards" and the lease time in the
network is

This is an update to my previous post, correcting an error of mine - I
think that the extra "dhclient" threads were created by the script that
was meant to be diagnosing the fault, not by NetworkManager.
Consequently, some of the reasoning was not valid. However, it may
still be true that

As niedzielski wrote on 2017-07-19:
It's clearly a IPv6 issue. Temp solution is to disable IPv6 until they
