Bootstrap-2 Rhino.Compute 7 Install SSL/TLS not trusted

[acmbo]

Hello,

currently try to install Rhino.Compute from Germany, Europe.

I'm getting a :

Exception calling "DownloadFile" with "2" argument(s): "The underlying connection was closed: Could not establish
trust relationship for the SSL/TLS secure channel."
At line:7 char:5
+     (New-Object System.Net.WebClient).DownloadFile($url, $output)
+     ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
    + CategoryInfo          : NotSpecified: (:) [], MethodInvocationException
    + FullyQualifiedErrorId : WebException

Comming from the bootstrap-2 shell script by the line

Download $downloadurl "$appDirectory/compute.zip"

in module_compute.ps1.

Its also seems that the URL https://nightly.link/mcneel/compute.rhino3d/actions/artifacts/2238862453.zip is blocked by Blueshield:

Dont know, if you guys can fix any of the issues. But it seems to be something i cant fix from my side.
