Hetzer and Let's Encrypt

Hey together,

I want to use DNS-01 from LE over Hetzner which works fine until it goes to the DNS record propagation. The error is a missing TXT record called "_acme-challenge..de" and as value I get different codes.

Now my question is if somebody knows what todo here, because normaly it should automaticly add this TXT record or am I wrong?

I use "traefik.http.routers.traefiks.tls.domains[0].main/sans" to add "mydomain.de" and "*.mydomain.de" to the list and as resolvers I use "" and ""

Any idea why it through an error on the TXT record?
