Unable to obtain ACME certificate for wildcard domains

Traefik Traefik v2 (latest)
1

Hi guys. I'm very new to Traefik and I'm trying to set up a wildcard certificate mechanism with traefik:v2.2 and GoDaddy. What I want to do is generating a valid certificate for the URLs pattern *.example.org. Here there is my docker-compose:

version: '3.7'

services:
  traefik:
    image: traefik:v2.2
    container_name: traefik
    restart: always
    env_file:

    volumes:

      - ./tls-certificates:/tls-certificates
    ports:
      - 80:80
      - 433:443
    networks:
      - web
    command:
      - --api.dashboard=true

      - --providers.docker=true
      - --providers.docker.exposedbydefault=false
      - --providers.docker.network=web

      traefik.http.middlewares.redirect-to-https.redirectscheme.scheme: https

networks:
  web:
      external: true

This is my .provider.env:

GODADDY_API_SECRET=foobarbaz
CERTIFICATES_EMAIL=bazbarfoo

It looks like I all set. However, I get this errors from the log:

}

How can I fix this?

Hello,

take a look to:

Hello @ldez thank you very much for your pointers.

As far I understood, my static configuration is ok:

      # --certificatesresolvers.<name> Certificates resolvers configuration
      # ACME V2 supports wildcard certificates. 
      # Wildcard certificates can only be generated through a DNS-01 challenge.
      # - --certificatesresolvers.mycoolwebsitechallenge.acme.tlschallenge=true
      - --certificatesResolvers.mycoolwebsitechallenge.acme.dnsChallenge.provider=godaddy
      - --certificatesResolvers.mycoolwebsitechallenge.acme.dnsChallenge.delayBeforeCheck=0
      # Email address used for registration.
      - --certificatesresolvers.mycoolwebsitechallenge.acme.email=foo@foo.org
      # Certificates storage
      - --certificatesresolvers.mycoolwebsitechallenge.acme.storage=/tls-certificates/acme.json

I tried to add the main and the sans entries to the router in the dynamic configuration of the traefik container (this is just for the dashboard):

labels:
  traefik.enable: true
  traefik.http.routers.traefikdashboard.rule: Host(`monitor.example.org`)
  traefik.http.routers.traefikdashboard.tls.certresolver: mycoolwebsitechallenge
  traefik.http.routers.traefikdashboard.tls.domains[0].main: "example.org"
  traefik.http.routers.traefikdashboard.tls.domains[0].sans: "*.example.org"
  traefik.http.routers.traefikdashboard.service: api@internal
  traefik.http.routers.traefikdashboard.middlewares: auth
  traefik.http.middlewares.auth.basicauth.users: foo:bar

but I'm still getting the same error. I do not understand where I am wrong.

Further info: if I look into my dns management panel in GoDaddy, I see an empty TXT called _acme-challenge (i.e., TXT value = null)

Any hint, or any working example, is really appreciated. Thanks

Well, I believe I'm getting crazy for this issue...

I do not understand either I'm misconfiguring something or if there's a problem on the let's encrypt/godaddy side.

Long story short. Static configuration:

      # --certificatesresolvers.<name> Certificates resolvers configuration
      # ACME V2 supports wildcard certificates.
      # Wildcard certificates can only be generated through a DNS-01 challenge.
      - --certificatesresolvers.wildcard-godaddy.acme.tlschallenge=true
      - --certificatesResolvers.wildcard-godaddy.acme.dnsChallenge.provider=godaddy
      - --certificatesResolvers.wildcard-godaddy.acme.dnsChallenge.delayBeforeCheck=0
      # Email address used for registration.
      - --certificatesresolvers.wildcard-godaddy.acme.email=foo@example.org
      # Certificates storage
      - --certificatesresolvers.wildcard-godaddy.acme.storage=/tls-certificates/acme.json

Dynamic configuration for the traefik dashboard

      - "traefik.enable=true"
      - "traefik.http.routers.traefik.entrypoints=webinsecure"
      - "traefik.http.routers.traefik.rule=Host(`traefik.example.org`)"

      - "traefik.http.middlewares.traefik-auth.basicauth.users=${DASHBOARD_USERNAME}:${DASHBOARD_PASSWORD}"
      - "traefik.http.middlewares.traefik-https-redirect.redirectscheme.scheme=https"
      - "traefik.http.routers.traefik.middlewares=traefik-https-redirect"

      - "traefik.http.routers.traefik-secure.entrypoints=websecure"
      - "traefik.http.routers.traefik-secure.rule=Host(`traefik.example.org`)"
      - "traefik.http.routers.traefik-secure.middlewares=traefik-auth"
      - "traefik.http.routers.traefik-secure.tls=true"
      - "traefik.http.routers.traefik-secure.tls.certresolver=wildcard-godaddy"
      - "traefik.http.routers.traefik-secure.tls.domains[0].main=example.org"
      - "traefik.http.routers.traefik-secure.tls.domains[0].sans=*.example.org"
      - "traefik.http.routers.traefik-secure.service=api@internal"

In my dns I have an A record * pointing to my ip.

This is the error I get:

traefik    | time="2020-04-15T16:41:22Z" level=error msg="Unable to obtain ACME certificate for domains \"example.org,*.example.org\" : unable to generate a certificate for the domains [example.org *.example.org]: acme: Error -> One or more domains had a problem:\n[*.example.org] acme: error: 403 :: urn:ietf:params:acme:error:unauthorized :: During secondary validation: Incorrect TXT record \"null\" found at _acme-challenge.example.org, url: \n[example.org] acme: error: 400 :: urn:ietf:params:acme:error:connection :: Connection refused, url: \n" providerName=wildcard-godaddy.acme

Edit:

On port 80 I have another nginx instance up & running (I'm gonna hide it behind traefik as soon as I fix this problem)

I have also disabled UFW (an ubuntu firewall).
Where am I wrong?

Thanx!

Could you clean your TXT records and retry?

A working docker-compose file:

version: '3.7'

services:

I think I find the issue, stay tune.

Ok I will! In the meanwhile, I'm gonna test your compose example.

Thanks for your help @ldez. Just tried your example, but I get the same error.

Cannot understand what is going on.

@floatingpurr could you open an issue here: https://github.com/go-acme/lego

thank you.

10

Ok I’ll do it. Can you just confirm that my configuration is fine?

11

your configuration is a bit verbose but right.

It's a bug with the godaddy implementation in lego.
I'm on it, but I need to find someone who can share with me a godaddy account, because I don't have a godaddy account.

12

Oh, ok thanks! Why verbose?

Ok I’ll open the issue in the lego repo. Regarding godaddy, I’m sorry but I do not have a shareable account.

Thanks for your support!

13

there is a workaround: add the GODADDY_SEQUENCE_INTERVAL env var to something like 120 (in second)

@Alan The implementation of the DNS challenge are really different between DNS providers.

So could you open another topic.

Hey @ldez, just tried adding GODADDY_SEQUENCE_INTERVAL=120 to your working docker-compose file but it did not fix the problem. Now I first get the error:

"Error while Peeking first byte: read tcp 192.168.128.2:80->13.65.201.223:51476: read: connection reset by peer"

Then, finally, as usual:

"Unable to obtain ACME certificate for domains "example.org,*.example.org" : unable to generate a certificate for the domains [example.org *.example.org]: acme: Error -> One or more domains had a problem:\n[example.org] acme: error: 403 :: urn:ietf:params:acme:error:unauthorized :: Incorrect TXT record "null" found at _acme-challenge.example.org, url: \n"

As mentioned also in this issue, the TXT dns record (i.e., _acme-challenge.example.org) appears during the process but then it is replaced by a null value.

Should this PR fix this problem?

Thanx once again.

17

Yes, that will fix the issue.

Great! Thanks!

Any workaround in the meanwhile?

20

Just a final question, by and large, do you know when the lego fix will be integrated in Traefik?

Thanx

21

Follow-up for those who arrive here.

The only way to "fix" I've found so far is using the TLS challenge in place of the DNS challenge for Go Daddy.

Well, actually it's is not a fix. Indeed, you cannot generate wildcard certificates in this way. If you don't have too much subdomains, it could be an acceptable workaround for being up&running while the actual fix comes up.

22

Hey @ldez, it worked in 2.2.1. Thanks!

P.S.: an empty TXT record is left in my GoDaddy DNS Management. Is it fine?
