Cause

Windows Server 2012 and earlier have TLS 1.2 disabled by default for WINHTTP. 

Resolution

In order to fix this issue, set TLS 1.2 as the DefaultSecureProtocol.  To do this:

1. Add the following two registry keys for 64-bit systems
2. Then reboot the system. 

[HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows\CurrentVersion\Internet Settings\WinHttp]
"DefaultSecureProtocols"=dword:00000800

[HKEY_LOCAL_MACHINE\SOFTWARE\Wow6432Node\Microsoft\Windows\CurrentVersion\Internet Settings\WinHttp]
"DefaultSecureProtocols"=dword:00000800
