Problem generating token on C#

Hi, I am trying to use the generateToken to acces my service. When my function tries to communicate with the server the program crash and drop me this error.

also here is my code.

public async Task AuthenticateService(int? desiredExpiration = null) { var tokenEndpoint =ServerUrl; var data = new Dictionary<string, string>(); data["username"] = Usuario; data["password"] = Password; data["client"] = "requestedip"; var content = new FormUrlEncodedContent(data); HttpRequestMessage msg = new HttpRequestMessage(HttpMethod.Post, "https://www.arcgis.com/sharing/rest/generateToken") { Content = content }; HttpClient httpClient = new HttpClient(); httpClient.DefaultRequestHeaders.Referrer = new Uri("https://arcgis.com"); var t = await httpClient.SendAsync(msg); var s = await t.Content.ReadAsStringAsync(); }

I have been stuck on this problem and try to solve it somehow but it seems to crush when the program try to communicate with the server.

Maybe you should take a look at Dave Timmins Anywhere.ArcGIS implementation. They solved a lot of token generations stuff using ArcGIS Online and ArcGIS Enterprise. I would start to inspect there Anywhere.ArcGIS.TokenProvider implementation.

Enjoy.
