Weytta.Client hangs waiting for web callback

[Matt]

Describe the bug

Weytta.Client waits indefinately for the server to post a callback to the listening port. The server (console log) indicates a successful authentication so the indefinite wait is unexpected.

To reproduce

With latest code,

1. Run the server
2. Run the client

• RunDemo.ps1 is also missing, I used https://github.com/mlhDevelopment/openiddict-samples/blob/dev/samples/Weytta/RunDemo.ps1

3. Continue in the client window to start the auth process
4. Note that the server window logs output and finally says "The authorization request was successfully validated"
5. Note that the client window does not log anything out

• Expecting either "An error occurred" or "Claims:"

6. If you debug into the Client project breakpoints after var context = await listener.GetContextAsync(); are never hit

Further technical details

Sadly I can't reproduce it as it works fine on my two dev machines... not sure what could be causing that.

[Matt]

Could it be a timing thing, where the response is completed so the listener cannot get the response?

[Kévin Chalet]

That's possible. Could you try moving the Process.Start in a separate thread (with a tiny Task.Delay to delay it a bit)?

[Matt]

I tried (something) and it didn't change anything. However, I have made progress utilizing the Velusia project so this is no longer needed.
