debian-live-testing download errors

I haven't been able to download debian using zsync. I keep on getting the
same error message. What am I doing wrong?


$ zsync
https://cdimage.debian.org/cdimage/weekly-live-builds/amd64/iso-hybrid/debian-live-testing-amd64-cinnamon.iso.zsync
failed on url
https://cdimage.debian.org/cdimage/weekly-live-builds/amd64/iso-hybrid/debian-live-testing-amd64-cinnamon.iso.zsync
could not read control file from URL
https://cdimage.debian.org/cdimage/weekly-live-builds/amd64/iso-hybrid/debian-live-testing-amd64-cinnamon.iso.zsync


Had to remove the s out of http to make it work any further than that.

No relevent local data found - I will be downloading the whole file. If
that's not what you want, CTRL-C out. You should specify the local file is
the old version of the file to download with -i (you might have to
decompress it with gzip -d first). Or perhaps you just have no data that
helps download the file

This goes for all of the zsynce files for debian-live-testing so the only
way that I can download it successfully is by downloading the .iso file
