Currenty I building a solution which is basically an integration between multiple external REST services. Since the solution is having multiple external service, I want to use the .NET ClientFactory to create HttpClients whenever they are wanted. Unfortunately an HttpClient instance created from the ClientFactory always results in an Unauthorized. This is a bit strange since directly creating a new HttpClient results in a success. I red the Microsoft documentation about the HttpClientFactory to determine the differences and possible use cases.
