PE Master install fails with "The node classifier could not be reached" error

I tried both RHEL (7) and Ubuntu images. I am able to replicate the issue on both instances. I can confirm that the issue exists across platforms and builds. However, I didn't get a chance to test 2015.1 build yet. I used 2016.1 package for both platforms. The installer ceases exactly at the below check point:

apt-get update -qq
PuppetDB configured.
Waiting for Node Classifier to start...

And fails with the below:
!!! WARNING: The node classifier could not be reached; please check the logs in '/var/log/pe-console-services/' for more information.

Apparently, the issue was reported here (https://tickets.puppetlabs.com/browse/ENTERPRISE-533) and was closed as resolved. But clearly the issue still persists. I tried working around by exporting:

export no_proxy="127.0.0.1,ichdummypuppet,ichdummypuppet.fq.dn,xx.xx.xxx.x,172.22.0.12"

But it seems to have little or no effect and the installer still freezes at this point. Any help on this would be great. Thanks.
