Downloads unavailable

All download links give ICAP Error. (https://step.esa.int/main/download/)

Does anyone have the Unix 64-bit Installer script for Sentinel Toolboxes? (http://step.esa.int/downloads/6.0/installers/esa-snap_sentinel_unix_6_0.sh)

I just tried the downloads and they work as expected. Are you behind a proxy or a firewall?
Maybe it must be configured?

Yep. That was it. Sorry. =)
