Description

The inability to download examples was reported by 3 different users (including myself) over the past week.

The other 2 reporters had just installed Qt DS for the first time, and are unable to download any examples
I had downloaded a few several months ago, and those can still be used (green icons in screenshot). But now I can't download any new ones (red icons in screenshot) on Qt DS 4.0.1. My internet connection is fine; disabling the firewall has no effect.
