The defaultGeneratedCert definition takes precedence over the ACME default certificate configuration. This default certificate should be defined in a TLS store: If no defaultCertificate is provided, Traefik will use the generated one. If Let's Encrypt is not reachable, the following certificates will apply: For new (sub)domains which need Let's Encrypt authentication, the default Traefik certificate will be used until Traefik is restarted. Since a recent update to my Traefik installation this no longer works, it will not use my wildcard certificate and defaults to the Traefik default certificate (this did not use to be the case) What did you see instead? This will request a certificate from Let's Encrypt for each frontend with a Host rule.

If Let's Encrypt is not reachable, these certificates will be used : Default Trfik certificate will be used instead of ACME certificates for new (sub)domains (which need Let's Encrypt challenge). In the example, two segment names are defined : basic and admin. When specifying the default option explicitly, make sure not to specify provider namespace as the default option does not have one. If Let's Encrypt is not reachable, these certificates will be used : ACME certificates already generated before downtime Expired ACME certificates Provided certificates Note Default Trfik certificate will be used instead of ACME certificates for new (sub)domains (which need Let's Encrypt challenge). If the valid configuration with certResover exists Traefik will try to issue certificates from LetsEncrypt. I've been trying to get LetsEncrypt working with Traefik, but unfortunately I continue to get the Traefik Default Cert instead of a cert provided by LetsEncrypt's staging server. I put it to test to see if traefik can see any container. Here's a report from SSL Checker reporting that secondary certificate, check Certificate #2 the one that says non-SNI: SSL Server Test: sample-custom-dc2.widemeshstaging.net (Powered by Qualys SSL Labs).pdf, For comparison, here's a SSL checker report but using HAPROXY Controller serving the exact same ingresses: How can I use "Default certificate" from letsencrypt? Youll need to install Docker before you go any further, as Traefik wont work without it. Both through the same domain and different port.
