Creative Cloud Packager Initializing Issue

When I install the latest CCP and start it up I get an issue after logging in where it times out on the loading page where it says "Initializing Creative Cloud Packager. This may take a few seconds." the times out to "Oops something went wrong, please try again"

I can see it has partially logged me in because my user name is in the top right corner under the shaded splash screen but it will not get past this and will not let me go any further.

We are using a proxy pac file for our network and I have had our networks team to see if anything is being blocked and it looks like it it trying to access an Amazon server of some sort? All of the usual adobe links have been white-listed but not these 3 attempts to the so called Amazon servers which it doesn't look like they want to go through the proxy and looks like they want to access it directly.

We cannot allow this to directly access out of the network due to security reasons and will not.

I cannot find anywhere to config to make it go through the proxy.

I have tried all of the usual stuff even closely related to this like renaming the OOBE folder and making sure I have the latest version, I have tried it on multiple machines but it still will not work.

I put one of the machines directly on an open ADSL line and opened CCP and it worked fine then I disconnected the ethernet cable then connected it back to our network and then I can use the CCP fine and download what I want but if I close the program whilst on the network and reopen it I get exactly the same problem.

I don't know why it is trying to connect to the above IP addresses..

HELP we have 16 users who we need to package up the latest versions.
