I'm having the exact same issue with a new Flex 200HP. Trying to upgrade the firmware via the initial setup wizard and despite being connected to the internet (I can browser websites, download files, etc.) the automated firmware upgrade process fails every time with "Download to your device failed".

Thanks for the info. Unfortunately none of the fixes listed worked. This has to be something related to this specific Flex 200.

I'm having the exact same problem as the OP @FordPrefect and I'm at a loss. I have an L2TP VPN connection on a USG Flex 200 that's been working fine for over a year with the Windows native VPN client. Then all of a sudden the other day it stopped working. Times out on "Connecting" and logs in the USG show similar entries…
