IPv6 issues

[gmlewis]

Emitter has been running locally on my Linux Mint Cinnamon 19.3 box for months now, and suddenly it refuses to start up.
The only thing I can think of is that Linux possibly flipped some switch from IPv4 to IPv6.
Here is the error:

$ cat emitter.conf

	"license": "OQ...wE:3",
	"limit": {},
	"tls": {

	},
	"cluster": {

		"advertise": "external:4000"
	},
	"storage": {
		"provider": "inmemory"
	}
}
