Comment 3 for bug 1876337

I am thinking the ipv6 issue is with our step-ca setup.
I think it is returning a URL containing the IPv4 address

was just taking a quick look at our config and it looks a little suspicious
e.g.
…
 "crt": "/home/cumulus/.step/certs/intermediate_ca.crt",
 "key": "/home/cumulus/.step/secrets/intermediate_ca_key",
 "address": ":8080",
 "dnsNames": [
  "128.224.196.78"
 ],
 "logger": {
  "format": "text"
 },
…

I think the dnsNames should be “acmeca.cumulus.wrs.com” .
