Can you please run engine-setup again and check if the URL of the POST request is still localhost? bug https://bugzilla.redhat.com/show_bug.cgi?id=1365744 was about running the setup twice in order to install this feature to work.
I seem to remember that I already did it, but I can do again.
Currently I'm on 4.0.2.
Is there any way to run engine-setup but without updating it to 4.0.3? ANy command line switch?
