DesiredSet - Replace Wait batch/v1, Kind=Job

I'm getting the following error in the system-upgrade-controller: "error syncing ... DesiredSet - Replace Wait batch/v1, Kind=Job "

when looking into the plan pod logs I can see the following error:

Error from server: Get "https://<machine ip>apply-<pod name>/upgrade": EOF

Do you have any idea what causes it ?

system-upgrade-controller version - v0.13.0 rancher/kubectl version - v1.23.3
