Unable to GetToken from QuickBooks QBOConceptsTutorial-DotNet Sample Application - token

Question

I am trying to learn how to work with QuickBooks API calls to integrate my own application with the platform's backend for invoicing and Customer records requests. I started with the Developer Web site from Quickbooks and landed on their GIT repository area, where I downloaded the QBOConceptsTutorial-DotNet Sample Application. Initially, the Application wowuld not start or load, failing on the HTTPS call. Therefore, I created a new similar applicaion on Visual Studio 2022 Community Edition and replicated all the necessary code to it. then my new application started properly and I was able to connect to my QuickBooks Sandbox Company with the Sandbox user id and secret credentials.
I received a callback set of variables with no errors. However, when I click on the Get Token model, the failure happened at the following new TokenClient() call. The error from the Web app is posted below. Can I get some assistance and guidance on solving this issue?
var tokenClient = new TokenClient(AppController.tokenEndpoint, AppController.clientid, AppController.clientsecret);
Line 68:{
Line 69: //Request Oauth2 tokens
Line 70: var tokenClient = new TokenClient(AppController.tokenEndpoint, AppController.clientid, AppController.clientsecret);
Line 71:
Line 72:
