Why enable middleware show 404 page not found

Traefik Traefik v2
1

I have create middleware like this:

apiVersion: traefik.containo.us/v1alpha1
kind: Middleware
metadata:
  name: reddwarf-jwt-auth
  namespace: reddwarf-pro
spec:
  plugin:
    forwardAuth:
      address: >-
        #
        http://dolphin-post-service.reddwarf-pro.svc.cluster.local:11014/post/auth/access_token/verify
        https://api.poemhub.top/post/auth/access_token/verify
      whitelist:
        - /public/*

when use the middleware in traefik 2.4.6 like this:

spec:
  entryPoints:
    - web
  routes:
    - kind: Rule
      match: Host(`tex.poemhub.top`) && PathPrefix(`/tex`)
      priority: 1
      middlewares:
        - name: reddwarf-jwt-auth
      services:
        - name: tex-service
          port: 8000

when access the url, told that 404 page not found. I am sure the authorize url is accessable. Am I missing something?
