Comment 1 for bug 1913348

Can you tell us more about the environment this is running in? Does your etcd unit have an IPv4 address?

The charm is getting that address from Juju, which is a bit unexpected, since Juju itself does not fully support IPv6 and requires IPv4 on the underlying hosts. It's obvious that the charm is not handling the address well, but I need to figure out if there is a misconfigured environment or a Juju bug underlying this.
