The connection is unexpectedly terminated with 200. And resume is not supported. Looks like a bug on server side.

These are working for me:

For the preview:

wget "http://download.slicer.org/download?os=linux&stability=any&offset=0" -O /tmp/slicer.tar.gz

For 5.8.1:

wget "https://download.slicer.org/bitstream/67c51fc129825655577cfee9" -O /tmp/slicer-stable.tar.gz

Maybe you have a proxy or other networking issue?

(edited to replace -o with -O)

I moved to another place with another ISP. There is a better speed, about 400KB/s, but the connection breaks too. It looks like I doesn’t reach 50% when it restarts.

I am not sure what is the server configuration, but judging that https://github.com/Slicer/slicer_download is Python app, it could be that Nginx breaks the connection under heavy load.

Now I was able to download slicer and the speed is much higher (3MB/s) than few hour ago when the download was broken.
