Siemens C450IP: Firmware update not possible

When I tried to update the firmware of a Siemens C450IP, I always got the following error:

Firmware update not possible: Server not available!

This is a known problem with some Zyxel routers, the really simple workaround is to change https://Gigaset.siemens.com/chagall with http://217.194.35.161/chagall, then press SET and finally click on Update Firmware.
