StipPrefix middleware does not work. "middleware \"ingress-mw-admin@kubernetescrd\" does not exist". What could be the reason for this?

Question

i followed this solution, which is also in line with my other research. But unfortunately it does not work.

i get 404 - 404 page not found when i run https://myhost.com/overview and when i log the traefik the following error message:

msg="middleware \"ingress-mw-admin@kubernetescrd\" does not exist" entryPointName=websecure routerName=websecure-registry-ingress-ingress-omyhost-de-middleware-api@kubernetes

does anyone have any idea what this could be?

my traefik deployment looks like that:

This is what i tried and added to the container arguments:

- --entrypoints.websecure.http.tls.options
- --entrypoints.web.http.middlewares=default-striper@kubernetescrd
