Can't get Linkstack docker working with Traefik (HTTP ERROR 418)

[cb3inco]

I'm bewildered that I can't get Linkstack (docker) with Traefik. Site doesn't load, nothing works when I access the domain. All I get is HTTP ERROR 418.

services:
  linkstack:

volumes:
  linkstack:
networks:
  traefik:
    external: true
    name: traefik

I've tried various fixes (commenting, uncommenting, downloading the .zip file and copying the files into the volume, etc.)

My domain is proxied through Cloudflare and my host is IPv6 only.

I've done enough setups with Traefik and none of this makes sense. What am I doing wrong?

When I review logs for the container it reads as such:

cat: can't open '/htdocs/version.json': No such file or directory

create a new file as dyn conf
with this content

http:
  serversTransports:
    noverifing:
      insecureSkipVerify: true

and add this as label
- "traefik.http.services.linkstack.loadBalancer.serversTransport=noverifing@file"

this are my labels -> and it works
