Have you idea why ?

kind: Middleware
metadata:
  name: authelia
  namespace: ${namespace}
spec:
  forwardAuth:
    address: http://authelia.authelia${internal_domain}:9091/api/verify?rd=https://auth.${domain}/
    trustForwardHeader: true
    authResponseHeaders:
      - Remote-User
      - Remote-Name
      - Remote-Email
      - Remote-Groups
