BITS Requires That The Server Support The Range Protocol Header

When trying to download Quickmap software or data using QDownloader or QSetup, you may get this error:

Quickmap Data Setup Failed

Download error: The server does not support the necessary HTTP protocol. Background Intelligent Transfer Service (BITS) requires that the server support the Range protocol header.

(Assuming you don’t have any network connectivity issues) this occurs because your firewall is blocking BITS from downloading the file. If you are using a Palo Alto firewall / router, this error is probably because you have blocked the HTTP Range protocol option, which is required for programs that start, stop / pause downloading then continue later, which part of the functionality of BITS (which is used by Quickmap to download data).
