Unable to change listening IP configured for juju controller 3.4

[David Negreira]

I found this issue on a juju controller running on LXD.
When I rebooted my machine, the Juju controller started with a different IP, and I was unable to use it or configure it with the new IP.
I tried to fix it by modifying the IP addresses configured on /var/lib/juju/agents/machine-0/agent.conf and /var/lib/juju/agents/unit-controller-0/agent.conf which seems to work fine.

The issue seems to be with the dqlite part of Juju,
When I start jujud-machine-0.service, which I always start after snap.juju-db.daemon.service, the 'Address' parameter on /var/lib/juju/dqlite/cluster.yaml is reset to the old value, and juju service continues trying to connect to the old IP address.

This is the error message which shows that it is trying to connect to the old IP:
