0x80190195 Status 405 when downloading google calender ics using bitsadmin

In a batch script I wrote:

Set src="http://calendar.google.com/calendar/ical/j<MORE>@gmx.net/private-c<MORE>e/basic.ics"
Set dst="D:\Data\ICS\basic.ics"
bitsadmin  /transfer myDownloadJob /download /priority normal %src% %dst%
pause

Instead of <MORE> there is actual information that I want to keep to myself.

Here is a screenshot that shows what happens when I call the batch script.

When I use the same URL in an internet explorer the download starts as expected. It does not matter for this error if there is a file D\Data\ICS\basic.ics

What am I doing wrong? Why is this not downloading the file?
