We have RPA running on 8 SP1. The Pega version we use does not currently support 19. Our organization recently turned off TLS 1.0 and 1.1 for certain requests. After that, one of the REST calls made by the automation began failing. The script I wrote runs a Process and calls the application through the command line. The app is a .NET console app that calls the REST service (custom app). The app works when called directly from the command line because it targets .NET 4.7.2 and the RPA machine has 4.7.2 installed. But when called from inside a robot automation, it fails with a WebException due to the SSL/TLS issue.

How can we fix the TLS version issue without upgrading to 19?
