Dear all,

If you are running BOINC on a Windows computer, please update to a new version (7.16.20) of the BOINC client. The previous version stopped working recently because of an expired SSL file that prevented it from communicating with several BOINC projects, with the BOINC server, and with Science United. You can download the new version here: https://boinc.berkeley.edu/download.php

With best wishes,

Windows communication failure: temporary workaround
Recently, the Windows BOINC client stopped being able to communicate with some projects and with Science United. This is because of an expired entry in a file called the "certificate authority bundle".

To fix this problem, download a new version of the file and put it in the

C:/Program Files/BOINC

Dann funktioniert auch die verheríge Boinc Version _ bei mir war es jedenfalls so - sollte auch nur ein gut gemeinter Tip sein

Why does it affect Windows, but not Mac and Linux computers ?

Linux automatically updates the certificates since they are an OS component.
On Windows, BOINC itself has to ship the certificates file and therefore it is only updated when BOINC is manually updated.

I assume Mac is similar to Linux.
