Bug Description
I have seen this in two different infrastructures, they were both running etcd on latest/stable channel (version 3.4.5) and running in a LXD container deployed by juju.
We first figured that this showing on the journalctl logs the following error message:
listen tcp 0.0.0.0:2380: socket: permission denied
Then we figured that the snap connections were missing, because when we were running `snap connections` nothing is returned related to the etcd unit.
The fix was to manually add the connections again with:
- sudo snap connect etcd:network-bind :network-bind
- sudo snap connect etcd:home :home
The issue seems to happen (ocasionally) after a reboot, but was unable to reproduce this yet on a test environment, but happened in a really short time within two different infrastructures.
