The install_compass script on Windows is currently unable to download the Compass installer .exe. It appears unable to negotiate TLS for some reason. We can test the ultimate command that fails (see the attached screenshot as well):
The download does seem to work in the Firefox and Edge web browsers, but curl also seemed to fail in negotiating TLS.
Perhaps the browsers are more lax... Did we make any recent changes to the TLS cert used for this API?
It may be that we need to add some additional code to the script, but the script was working as-is AFAIK.
