• Yes, I've searched similar issues on GitHub and didn't find any.
• Yes, I've searched similar issues on the Traefik community forum and didn't find any.

What did you expect to see?

As reported by let's encrypt, the provider is fully supported

Here is the official let's encrypt api documentation

Hello,

Traefik uses lego to handle ACME challenges.

Could you open an issue here?

FYI acme.sh is neither the official Let's Encrypt documentation nor the official Shellrent API documentation, it is just an ACME client.

Also the link you provided is not an official Let's Encrypt communication but a just a post on the Let's Encrypt Forum that lists the DNS supported by ACME client.

I see, thanks for all the info, totally my bad there.

I'll open an issue on lego, you can close this one.

Thank you
