I am attempting to query data that has been loaded into ArcGIS in the form of layers.
I am attempting to query out basic data (Any data at this point) from a imported Layer. I think the error is with my .Net code and how I set up to attempt the query but I seem to run into errors when I attempt to query data that is present in the tutorial.
Code Below:
public async static Task QuerySantaAnaData()
{
string tokenString = ""; //This is generated on the the Dashboard for ArcGIS for Developers page under Temporay Access Token
string path = @"https://services3.arcgis.com/{My ID}/ArcGIS/rest/services/{Service Name}/FeatureServer/0/query?where=FID>0&outFields=*";
try
{
using (HttpClient client = new HttpClient())
{
client.Timeout = new TimeSpan(0, 1, 0, 0);
client.DefaultRequestHeaders.Add("Token", tokenString);
using (HttpResponseMessage response = await client.GetAsync(path))
{
using (HttpContent content = response.Content)
{
string data = await content.ReadAsStringAsync();
}
}
}
}
catch (Exception e)
{
Console.WriteLine(e.Message);
}
Console.ReadKey();
}
The Inner Exception I receive is
{System.Net.WebException: The underlying connection was closed: An unexpected error occurred on a send. ---> System.IO.IOException: Authentication failed because the remote party has closed the transport stream.
at System.Net.TlsStream.EndWrite(IAsyncResult asyncResult)

at System.Net.ConnectStream.WriteHeadersCallback(IAsyncResult ar)
--- End of inner exception stack trace ---
at System.Net.HttpWebRequest.EndGetResponse(IAsyncResult asyncResult)
at System.Net.Http.HttpClientHandler.GetResponseCallback(IAsyncResult ar)}
I have even attempted to perform this API request with the example data that ArcGIS provides in their tutorials here https://developers.arcgis.com/labs/rest/query-a-feature-layer/
