Hi everyone!
I’ve just wanted to learn how to use 3D Slicer, but unfortunately, I can’t download the Sample Data.
I always receive this:
Requesting download CT-cardio.seq.nrrd from [https://github.com/Slicer/SlicerDataStore/releases/download/SHA256/d1a1119969acead6c39c7c3ec69223fa2957edc561bc5bf384a203e2284dbc93](https://github.com/Slicer/SlicerDataStore/releases/download/SHA256/d1a1119969acead6c39c7c3ec69223fa2957edc561bc5bf384a203e2284dbc93) …
Download failed:
Download failed (attempt 3 of 3)…
Thank you for your help!

It works for me - maybe you are behind some kind of institutional firewall or proxy?
