My service looks like this

namespace Poul.Erik.Modules.ModulDatabase.Services
{
    public class ImageController : DnnApiController
    {
        public ImageController() { }
        
        [DnnAuthorize(AuthTypes = "JWT")]
        [HttpGet]
        public HttpResponseMessage GetAllModules()
        {
            try
            {
                //Load Data Into List
                var moduler = ModulManager.Instance.GetModuler(ActiveModule.ModuleID).OrderBy(m => m.ModulNavn, StringComparer.CurrentCultureIgnoreCase);

                //Convert List Into JSON
                var jsonModules = JsonSerializer.Serialize(moduler);

                //Create a HTTP response - Set to OK
                var res = Request.CreateResponse(HttpStatusCode.OK);

                //Set the content of the response to be JSON Format
                res.Content = new StringContent(jsonModules, System.Text.Encoding.UTF8, "application/json");

                //Return the Response
                return res;
            }
            catch (Exception exc)
            {
                return Request.CreateErrorResponse(HttpStatusCode.InternalServerError, exc);
            }
        }
    }
}

The RegisterRoutes look like this

public void RegisterRoutes(IMapRoute mapRouteManager)
        {
            mapRouteManager.MapHttpRoute(
                moduleFolderName: "ModulService",
                routeName: "default",
                url: "{controller}/{action}",
                namespaces: new[] { "Poul.Erik.Modules.ModulDatabase.Services" });
        }

I have testet the routing just using a web browser and the result proows thathe service can be reached, but requires authentication:

Authorization has been denied for this request.

So far so good.

Next the windows app:

await ProcessRepositoriesAsync(httpClient);

static async Task ProcessRepositoriesAsync(HttpClient client)
{
    var values = new Dictionary<string, string>
    {
        { "u", "......." },
        { "p", "............" }
    };

    var content = new StringContent(JsonSerializer.Serialize(values), Encoding.UTF8, "application/json");

    var response = await client.PostAsync(("http://development911.dnn...mobile/login"), content);

    if (response.StatusCode == System.Net.HttpStatusCode.OK)
    {
        var responseString = await response.Content.ReadAsStringAsync();

        var LoginResultData = JsonSerializer.Deserialize<LoginResultData>(responseString);

        if (LoginResultData != null)
        {
            client.DefaultRequestHeaders.Authorization = new AuthenticationHeaderValue("Bearer", LoginResultData.accessToken);
            client.DefaultRequestHeaders.Accept.Add(new MediaTypeWithQualityHeaderValue("application/json"));

            response = await client.GetAsync("http://development911.dnn...etAllModules");

            if (response.StatusCode == System.Net.HttpStatusCode.OK)
            {
                responseString = await response.Content.ReadAsStringAsync();
            }
        }
    }

The post resuest for getting the token suceeds, but the get request fails with 401.

This wrom the IIS log:
2023-02-04 11:52:44 127.0.0.1 POST /API/JwtAuth/mobile/login - 80 - 127.0.0.1 - - 200 0 0 51
2023-02-04 11:52:49 127.0.0.1 GET /API/ModulService/Image/GetAllModules - 80 - 127.0.0.1 - - 401 0 0 13

DNN version is 9.11.0,

IIS is running on my local machine

The windows app is a console app targeting .NET 6

Tha app is also running on my local machine

I hope somone can help me out.

Thank you in advance
