DuckDNS Lets encrypt addon for hassio setup problems?

Ive filled in everything, but this is the error it comes out with

Details:
{
“type”: “urn:acme:error:malformed”,
“detail”: “Error creating new authz :: DNS name does not have enough labels”,
“status”: 400
}

Just ran into this as well. Your domain needs to be the FQDN, rather than just the subdomain that you’d use for just HTTP.

Ex: “domains”: [
yourdomainname.duckdns.org
]
