npgsql: Specified SSL Protocol Type is not Valid

I am using an application that is imbedded within Autodesk Revit levering their open API. I have worked inside this context for a couple years and connected to other industry DB platform without any issues.

1. I have the application that makes a call to another dll (pgRDG)

using Autodesk.Revit.Attributes;
using Autodesk.Revit.DB;
using Autodesk.Revit.UI;

namespace RDG_Revit_2022.Testing
{
	[Transaction(TransactionMode.Manual)]
	class Test : IExternalCommand
	{
		public Result Execute(ExternalCommandData commandData, ref string message, ElementSet elements)
		{
			UIApplication uiapp = commandData.Application;
			Document doc = uiapp.ActiveUIDocument.Document;

			//This is the external reference call
			pg.RDG.Connection.Testing();
			return Result.Succeeded;
		}
	}
}

2. Then here is the Testing() method.

using System;
using System.Windows;
using Npgsql;

namespace pgRDG
{
	public class Connection
    {
        public static void Testing()
		{
			string ConnString = "Server=name.postgres.database.azure.com;Database=dbName;Port=5432;User Id=uid;Password=pw;Trust Server Certificate=true;Ssl Mode=Require";
			using(NpgsqlConnection conn = new NpgsqlConnection(ConnString))
			{
				try
				{
					conn.Open();
					NpgsqlCommand cmd = new NpgsqlCommand("SELECT * FROM tableName", conn);
					NpgsqlDataReader reader = cmd.ExecuteReader();
					while(reader.Read())
					{
						MessageBox.Show(reader.GetString(reader.GetOrdinal("command")));
					}
				}
				catch(Exception ex)
				{
					MessageBox.Show(ex.ToString());
				}
			}
		}
    }
}

The issue

1. When I run this I receive the following error:

If I run this exact same code from a desktop application it connects fine, but always produces this error within the Revit context.

I have also created a request on the Autodesk forums thinking someone there may have an idea as well. https://forums.autodesk.com/t5/revit-api-forum/revit-2022-environment-preventing-ssl-handshake-with-postgresql/td-p/10304990
