New .NET Agent Install Causing TLS Errors and Application Issues

Hi,

I created a new application for AppD for my system's UAT environment. These are Windows Server 2019 IIS web and application servers with the .NET agent.

After installing the AppD .NET agent and having it running, it does report back to the controller, but we observed new errors in our application and the business process we are trying to run is failing with this:

Full Error Message: System.Net.WebException: The request was aborted: Could not create SSL/TLS secure channel.

If I disable AppD, then the process works and the TLS error goes away.   So AppD is actually causing an impact on our environment. Any ideas on how I can fix it?
