Is it the proxy server or is it the app?

Question

I downloaded the Creative Cloud desktop app last week. During the download I was asked for my proxy server ID and password. I entered them and clicked the "Remember me" box. The app installed and started up, and asked for the same information. I entered it and clicked "sign in". The DL center came up and  I managed to download a couple of apps, although the "enter your proxy server ID" screen on the CC app popped up (on average)  every thirty seconds or so -- fortunately, I could just hit return to start the DL back up.
Yesterday and today, though -- not even that. Rather than starting the download center, it just refreshed the sign-in page. I have re-entered my proxy info, in case I mis-typed my password; I have tried both WITH and WITHOUT a domain prefix (as in XX\Username}, all to no avail.
I even uninstalled the CC app and re-installed it (albeit from the same disk image) but the problem persists.
The fact that I can DL the CC app, and DID manage to DL the other apps last week certanly implies to me that Adobe isn't being blocked by the work firewalls. If I'm off-base, here, then I'm not sure how to reconcile the two conflicting results.
If my proxy serttings let me download the CC app (and other software off the web), shouldn't those same settings work WITH the app? What am I missing, here?

Answer 1

Hi, Jeff --
There are a couple of reasons why I haven't pestered them, yet:
1 -- I'm just trying to figure out why downloding worked last week but not this week. Because the obvious answer from MIS is "We haven't changed anything since it was working before, so the problem isn't on our end. If the downloader isn't working, you should check with the manufacturer, first." I'm trying to forestall that by making sure that I have tried everything possible from my end before passing it on to them
2 -- Everything on the linked page seems to be aimed at larger set-ups where the IT group is the central repository for administering software across the enterprise. In this case hey're not deploying the software. I'm the admin and (at the moment) sole user, so that doesn't seem to apply. I'm just using the servers as "dumb pipes", so I'm not sure I see anything linked there that would help. Of course, it's possible that I missed something amd -- once I've convinced myself that I've covered every possibility that I could -- I'll pass that link on to them.
Partly, I was just wondering if anyone else had run into that "now you can/now you can't" issue with downloading, since it wasn't in the FAQs.
Thanks;
