Matt Peterson - 9/1/2020

One of my participants received this error:

System Error 12045: The certificate authority is invalid or Inccorect Line 260, File win\Path_win.cpp
Unable to open file "https://scripts.millisecond.com/mpeters2/moa2020/moa-lab1-2020.iqx"

That's a client-side certification validation issue, which can have many disparate causes ranging from the participant's device being set to a wrong date, misconfiigured internet options, a broken certificate store or explicitly not trusing the Amazon Root CA, to being behind a MITM proxy.
