After making registry changes to disable TLS 1.0,1.1 and enable TLS 1.2 only our "Powershell - Run Script File" actions are failing. These scripts download files from a source repository via http.
Release : 6.7
The powershell script attempting to download a file is using the Net.WebClient powershell class. The change made at the operating system level, through the registry updates, also limits powershell.
Discuss this problem with your Powershell script developer. They may want to consider adding a line to the powershell script similar to this:
[Net.ServicePointManager]::SecurityProtocol = [Net.SecurityProtocolType]::Tls12;
