Description

Unit test ValidateHttpListenerRedirectUriAsync is flaky and intermittently fails with a connection refused error when attempting to send a request to localhost. This occurs because the HTTP listener is not always fully initialized before the test attempts to send a request.

Solution

• Ensure the listener is ready before sending the request.

• Use Task.WhenAny(listenTask, Task.Delay(5000)) to check if the listener completes within the timeout.

• Introduce a small delay (await Task.Delay(500)) before sending the request to allow the listener to start properly.
