How to config acme-dns wildcard cert

Using this GitHub - caddy-dns/acmedns , I tring to config the wildcard

My config like this

{
	#auto_https disable_redirects
	#auto_https off

	http_port 80
	https_port 443

	log {
		output stdout
		level INFO
		format console
	}

  # _acme-challenge.example.com
	acme_dns acmedns {
		config {
			example.com {
				username ""
				password ""
				subdomain ""
				fulldomain ".auth.acme-dns.io"
				server_url "https://auth.acme-dns.io"
			}
		}
	}
}


*.example.com example.com console.example.com {
	respond / "Hello World" 200
}

there is more console.example.com block generated by docker-proxy, caddy still tring to resolve the cert for console.example.com

tls.obtain	will retry	{"error": "[console.example.com] Obtain: [console.example.com] solving challenges: presenting for challenge: adding temporary record for zone \"example.com.\": Config for domain console.example.com not found (order=https://acme-staging-v02.api.letsencrypt.org/acme/order//) (ca=https://acme-staging-v02.api.letsencrypt.org/directory)", "attempt": 3, "retrying_in": 120, "elapsed": 186.085659, "max_duration": 2592000}

but www.example.com already using the wildcard cert

I see there is tls.dns config, I really have no idea how to config caddy to using a wildcard cert, I hope I just config the cert once, then all domain match the wildcard should use the cert.

You can’t use fake domains like example.com, you need to use a real public domain.

Are you actually using the ACME-DNS service? Did you follow the steps in those docs to sign up for an account?

You don’t need to specify console.example.com because *.example.com already covers it.

I’m not sure what you’re trying to do with that.

Hi @wener,

example.com is the proper domain name to use if you redacted the actual domain name.

As https://example.com/ shows the intended usages

Example Domain
This domain is for use in illustrative examples in documents. You may use this domain in literature without prior coordination or asking for permission.
