Asset Store: 407 proxy authentication error

We've been dealing with this problem for a while now and it does not appear that anyone else is having this problem, or, there doesn't seem to be a solution that we can find.

Main problem: Receive a 407 proxy authentication error while trying to download assets from the asset store.

Situation: 1. Working from a school network behind a proxy server. 2. Network is administered through RES Powerfuse 3. Unity is a trusted site, allowed to bypass the proxy

This does not solve the problem. Various solutions have been tried (setting/overriding Windows/IE settings etc.)

What did work (temporarily and partly): 1. Looking in the network card to find the address it was actually trying to reach, which turned out to be an amazon cloud server 2. Adding this cloud server to the trusted list 3. Quite a few assets could now be downloaded, presumably those not accessible resided on a different cloud server

Current problem: 1. Back to square one, no assets can be downloaded 2. Possibly assets moved to a different cloud server (have to bring in external help to look at this if nothing else works)

Requests/possible solutions: 1. Is there a setting within unity that will allow it to not use the proxy server at all? 2. Is there a list somewhere of what servers the assets are actually stored on? 3. Any kind of plugin available that will allow unity to bypass the proxy? 4. Any other kind of solution

Thanks,

Paul
