in CMD

curl -v http://ocs.xxx.de/download/1549636537/1549636537-1

i'm on the right way. The Problem ist the SonicWall between 2 VPN Locations.Murphys Law is the Problem - Firmware oder ContentFilter, AntiVirus makes the Problem and not the Setup of a new Client.
Other Clients on this Location have the same Problem since a few weeks.

Download from the webinterface is ok - https
Download form the /download Folder with https ist ok - with http the file is corrupt or won't download

How can i switch to https download wenn deploying a packet?

I try to configure the SonicWall
