Jenkins 403 pipline plugin

Hi All,

I am trying to set up jenkins with helm. The deployment works but I am running into a 403…

So the basic install is with these plugins:

    - azure-ad:476.vd1c42682ea_6a_  
    - azure-keyvault:251.vcfe31c013dc7


  # -- Used for label
  componentName: "jenkins-controller"
    # -- Controller image registry
    registry: ""
    # -- Controller image repository
    repository: "jenkins/jenkins"

    # -- Controller image tag override; i.e., tag: "2.440.1-jdk17"
    tag: '2.457-jdk17'

This lets me login and manage jenkins. after then installing:

Now when you try to configure the plugin you get this in the console:

Pressing save will get you this the oops page with an ID.
This log ID will give you these logs:

After a few days of tryig to get this to work I am running out of options… Anyone got a usefull hint / tip to get this resolved?
