Environment

ITMS 8.5, 8.6, 8.7

Cause

The actual NS logs showed the issue:

Download failed for: http://officecdn.microsoft.com/pr/7ffbc6bf-bc32-4f92-8982-f9dd17fd3114/office/data/16.0.14931.20944/i640.c2rx

The remote server returned an error: (503) Server Unavailable.

In this particular scenario, the admin didn't have access to the desired location. 

Resolution

To test if you actually can access the file directly from a browser on your SMP Server (use the same URL from the example logs entries above):

http://officecdn.microsoft.com/pr/7ffbc6bf-bc32-4f92-8982-f9dd17fd3114/office/data/16.0.14931.20944/i640.c2rx

http://officecdn.microsoft.com/pr/7ffbc6bf-bc32-4f92-8982-f9dd17fd3114/office/data/16.0.14931.20944/stream.x86.x-none.dat

After trying to access the links that you needed to download the patch files and found that the firewall was blocking access. When implementing the proper firewall rules it allowed access to the files.
