TLS 1.0 and 1.1 Deprecation

A. AWE(Automate 10) uses SChannel. This means that it relies on the Windows operating system instead of its own SSL library. This means you likely will be affected on Deprecated versions of Windows such as Windows Server 2008 and Windows Server 2012. There are methods to change the default protocol version in these operating systems. You can find a Microsoft article of how to do that here.
