A common issue run into is a mismatch in TLS versions. This is usually caused by disabling TLS version 1.0 on your machine. Windward supports TLS versions 1.0-1.2 so if running into a version issue, running the following registry script will remedy issues using newer versions of TLS configured by the OS.
For more information about the registry script and TLS please see the following:
