Last.fm source showing "Auth Interaction Required" on DNS errors

[megatwig]

Describe the bug
multi-scrobbler is treating EAI_AGAIN DNS errors as authentication errors and asking for reauthentication, but a retry is all that's needed.

If my container starts up while my network connection is offline, it hits a DNS error and never retries, and just sits there doing nothing until I realize and go reauthenticate it (or restart the container). I also have a webhook configured that also hit a DNS error so couldn't send out a notification.

To Reproduce

1. Configure Last.fm as a source
2. Start the container with no internet connectivity (e.g. internal: true on a Docker network)

Expected behavior
A network (/DNS) error when testing Last.fm authentication should be retried, as other client initialization requests are. Probably also the same for webhooks.

MS is likely being run in a container with BRIDGE networking which means the above addresses are not accessible from outside this container.
To ensure the container is accessible make sure you have mapped the *container* port 9078 to a *host* port. https://foxxmd.github.io/multi-scrobbler/docs/installation#networking
The container will then be accessible at http://HOST_MACHINE_IP:HOST_PORT
