Valid access token still getting a 401

Thank you so much for your quick response. Still haven’t figured out the problem but at least I have something to look at. There is indeed a Authorize attribute, and roles can be specified. But in my case I have none yet.

    [Route("api/1.0/things")]
    [Authorize]
    public class Controller: BaseController
    {
    // More code

I will try to dig deeper into the authorization in the dotnet core app.
