I'm trying to sync the Ubuntu 13.04 daily ISO according to this answer. I've used this command:
zsync http://cdimage.ubuntu.com/daily-live/current/raring-desktop-amd64.iso.zsync
It worked the first time I ran it and I was able to download the entire ISO. However, any time I run it again, it fails with this error:
$ zsync http://cdimages.ubuntu.com/daily-live/current/raring-desktop-amd64.iso.zsync
#################### 100.0% 13.5 kBps DONE

EDIT: I just tried again and got this error:
##################-- 90.3% 54.7 kBps 24:29 ETA bad status code 408
##################-- 90.3% 24.2 kBps aborted
I also tried downloading it again in a different directory, and got the same "connection refused" message twice. So it isn't just a problem with syncing already downloaded ISOs.
I've tried deleting the ISO and restarting, and also using the i386 version.
How can I fix this so I can sync an Ubuntu 13.04 ISO using zsync? Or is their a better way to sync an development ISO?
