[SOLVED] Identity Server 4 ASP.NET Quickstart 'refused connection'

Identity Server 4 ASP.NET Quickstart 'refused connection'

I'm following the Identity Server 4 Quickstart and I'm having a weird issue even though I followed it step by step.

It says (translated from German) connection denied by target computer. Whats weird about this is that in the API project "we"(I) said ValidateAudience = false which I thought meant that tokens aren't being validated at all.

// call api
var apiClient = new HttpClient();
apiClient.SetBearerToken(tokenResponse.AccessToken);

var response = await apiClient.GetAsync("https://localhost:6001/identity");
if (!response.IsSuccessStatusCode)
{
    Console.WriteLine(response.StatusCode);
}
else
{
    var content = await response.Content.ReadAsStringAsync();
    Console.WriteLine(JArray.Parse(content));
}

I am truly confused.The Client does get an accessToken so that's not the problem ... I hope.

Solution

So in API/Properties/lauchsettings .... when generating the project it used a default sheme and in that sheme it sets a port of 43033 or smth
