RESTClient Basic Auth. funkt nicht

[Union]

Ich habe jetzt noch mal einen kleinen Test aufgesetzt. Funktioniert.

Delphi-Quellcode:

uses
  REST.Client,
  REST.Types,
  REST.Authenticator.Basic,
  IPPeerClient,
  IPPeerAPI;

procedure TestRestClient;
var
  Client  : TRESTClient;
  Request : TRESTRequest;
begin
  Client := TRESTClient.Create('https://httpbin.org/');
  try
    Request := TRESTRequest.Create(Client);
    try
      Request.Method := TRESTRequestMethod.rmGET;
      Request.Resource := 'uuid';
      Request.Execute;
      Writeln(Request.Response.Content);
    finally
      Request.Free;
    end;
  finally
    Client.Free;
  end;
end;
