You are configuring a custom availability monitoring tool that runs as a continuous background process on an internal server. The tool executes health checks and uses the Azure Application Insights SDK to report results. You use the following class to send telemetry:

csharp
using Microsoft.ApplicationInsights;
using Microsoft.ApplicationInsights.DataContracts;

public class HealthReporter
{
private static TelemetryClient telemetryClient = new TelemetryClient();

public static void SendResult(bool success)
{
var availability = new AvailabilityTelemetry
{
Name = "InternalApiTest",
Success = success,
RunLocation = "CorporateNetwork"
};
telemetryClient.TrackAvailability(availability);
}
}

Although the background process runs continuously and calls the `SendResult` method, no availability data appears in the Azure Portal, and no exceptions are logged locally.

Which of the following is the most likely cause of this issue?
