Automatic certificates - Warning "Error while creating certificate store"

Traefik Traefik v2 (latest)
,
1

Hello,

I'm trying to setup automatic certificates on my Traefik setup. It seems to work as I get a valid secured connection to my services, bu I always have an error when starting traefik.

level=error msg="Error while creating certificate store: unable to find certificate for domains \"*.mydomain.io,mydomain.io\": falling back to the internal generated certificate" tlsStoreName=default

Running in debug, I can see a few line I have the following which makes me think it loaded the certificates in some way ?

level=debug msg="Default ACME certificate generation is not required." providerName=ovhresolver.acme

Setup:

  • Traefik 2.10.3 running in a docker container

Here are my configuration files:

My docker-compose file mounting the volume for certificate storage

   volumes:
      - "/var/run/docker.sock:/var/run/docker.sock:ro"
      - ${VOLUMES}/traefik:/etc/traefik/
      - ${VOLUMES}/traefik/acme/:/etc/traefik/acme

In can see the acme.json file in the host traefik/acme volume and it looks legit. So generating the cert definitely worked.

traefik.yml

# Providers an entrypoints omitted for brevity

    ovhresolver:
        acme:
            email: myemail
            storage: "/etc/traefik/acme/acme.json"
            dnsChallenge:
                provider: ovh
                delayBeforeCheck: 10

          sans:
            - "*.mydomain.io"

Is there something wrong in the configuration ?
