1. Environment

1a. Operating system and version

Windows 10

1b. Caddy version (run caddy version or paste commit SHA)

v2.8.4 h1:q3pe0wpBj1OcHFZ3n/1nl4V4bxBrYoSoab7rL9BMYNk=

1c. Go version (if building Caddy from source; run go version)

go version go1.23.0 windows/amd64

2. Description

2a. What happens (briefly explain what is wrong)

Caddy v2.8.4 fails DNS challenge on subdomain zone.

2b. Why it's a bug (if it's not obvious)

If I downgrade to Caddy v2.7.6, Caddy is able to pass DNS challenge. The earliest version I observed this issue is on Caddy v2.8.0. I noticed in the logs when Caddy fails DNS challenge, there is no wait between waiting for solver before continuing and done waiting for solver. When Caddy passed DNS challenge, the wait is over a minute.

2c. Log output

Failed to pass challenge to obtain certificate

3. Tutorial (minimal steps to reproduce the bug)

  1. xcaddy build --with github.com/caddy-dns/desec
  2. Create Caddyfile (remove DELETE THIS within token)
{
	debug
	acme_ca https://acme-staging-v02.api.letsencrypt.org/directory
}
# Wildcard DNS for any IP Address method
*.ip.geah.dedyn.io {
	tls {
		dns desec {
			token "JhnM6BVwDELETEq7Dp3HBUtDweKeTHIScmsWGY"
		}
		propagation_delay 80s
	}
	# Fallback for otherwise unhandled domains
	handle {
		respond "git gud" 403 {
			close
		}
	}
}
  1. caddy run

Interesting, that's very odd!

Does this only happen with Desec? I'd be curious if you happen to be able to test another (similar?) domain on another DNS provider (I appreciate that you gave the recipe to reproduce it, I just don't have extra time right now).

Haha! Yeah it's indeed odd. In hindsight, I should have elaborated that the DNS-01 failure is specifically on the subdomain _acme-challenge.ip.geah.dedyn.io which on a separate zone from the apex domain geah.dedyn.io zone. The apex domain passes DNS challenge fine.

Right now I can only see this issue on deSEC since it's the only DNS provider that offers free subdomain setup. Other provider like Cloudflare has it at Enterprise tier pricing! So I can't config 2 separate zones. Let me know if there another provider that offer it for free I can test on.

I hope another member of the org can take a look at this issue.

my fault, mosdns in my router not work correctly, caddy work fine after stop mosdns.

I can confirm that this was an issue for me as well.

I tried to use the dns digitalocean plugin and it flatly refused to obtain certificates using Caddy v2.8.4

I switched to a build with v2.7.6 and it successfully obtained a certificate with dns-01 challenge using the digitalocean API within a few seconds.

I think this is fixed in the latest beta (2.9 beta 3) if you would like to try it and confirm. caddyserver/certmagic@4293198
