Prevent Traefik from creating Letsencrypt certificates for non configured domains / subdomains


we have Traefik with a wild card subdomain at the Domain Registrar. But Traefik now starts to create certificates for any given domain that ever exists. We just got blacklisted from Letsencrypt again because Bots call random subdomains.

We are setting and domain on the fly within Docker Compose files. But even so it should be possible to prevent Traefik from using any SSL on any non configured domain.

Anyone knows a way to set this up or any other way to prevent Letsencrypt certificates to be created for any random subdomain?

This there seems no solution for this task, i've switched back from wildcard domains to single set domains within the domain registry. I don't think this is a good solution as this should be handled with Traefik.
