When trying to pair a Flex 2 dev device to a Windows Server 2012 R2 machine we get the above error. I verified the correct certificates are in place. This seems to only happen on Windows Server 2012 machines as we can pair the device fine in Windows 10. We have reproduced this consistently on 2 different Windows Server 2012 machines. Is this a known issue with this OS or is there something else I can do to troubleshoot?
