I am testing PDI 8.3 and started my carte server on the localhost. When starting a job from Spoon and sending it to the carte server, I get the error message

HTTP Status 401 - http://localhost:8190/localhost/kett...ad=jb_loop.kjb - Unauthorized

user names, passwords are all set to "cluster" in spoon and the carte config file.

Any ideas what might be causing this?
