I am hosting a site for a friend with a different domain name than mine.  
The domain is: [https://www.garagedecheseaux.ch/](https://www.garagedecheseaux.ch/)

I forgot to save the acme.json file once the certificate was validated and I restored acme.json which did not have the key for this domain.

Now, for this domain, I have a CN=TRAEFIK DEFAULT CERT. How do I get my certificate?

I see that my old one has expired: [crt.sh | 5425180323](https://crt.sh/?id=5425180323)

Thank you very much

Sorry, I resolve now my problem 😅

but I would still like some information. Is there a command with traefik to test certificates and force renewal? Or if I understand correctly, I have to delete the entries in acme.json and restart traefik?

Thanks for your information.

Check [Traefik Let's Encrypt configuration examples](https://doc.traefik.io/traefik/https/acme/#configuration-examples) on how to setup the LE certificate process within Traefik.

```auto
# traefik.yml or command line params

entryPoints:
  web:
    address: ":80"
  websecure:
    address: ":443"

certificatesResolvers:
  myresolver:
    acme:
      email: your-email@example.com
      storage: acme.json
      httpChallenge:
        # used during the challenge
        entryPoint: web

log:
  level: DEBUG

accessLog: {}

```

Additionally you need to create the router referencing `myresolver`, either in dynamic.yml or via labels when using service discovery.

If it does not renew, enable and check [Traefik logs](https://doc.traefik.io/traefik/observability/logs/) and set them to debug, check [Traefik access logs](https://doc.traefik.io/traefik/observability/access-logs/). Make sure the validation works. In general you get a new certificate, so you don't need an old one.
