I think the external reverse proxy is the key - I don’t think this is solvable at all, or at least not easily, from just within the Docker container.

I’ve solved it now by having the Discourse Docker listen on a Unix socket and front it with a Caddy on the same machine (_outside_ Docker). The Caddy setup is trivial, includes Let’s Encrypt, and now it works as expected for IPv6 as well.

```plaintext
forum.example.com {
  proxy / unix:/var/discourse/shared/web-only/nginx.http.sock {
    transparent
    websocket
  }
}

```
