PI Web API Unable to Establish Trust

I am using sample C# code from OSI:


pi = "PI Server Name";

string tag = "sinusoid";

string baseURL =;

string url = baseURL + "/points?path=\\\\" + pi + "\\" + tag;

HttpWebRequest webrequest = (HttpWebRequest)WebRequest.Create(url);

webrequest.ContentType = "application/json";

webrequest.UseDefaultCredentials = true;

webrequest.Method = "GET";

HttpWebResponse webresponse = (HttpWebResponse)webrequest.GetResponse();


The PI Server Name is the name that shows up in my PI SDK Connections dialog.  I am successful at getting the PI Web API help file using the baseURL.  I am not a PI admin, but have been told we use Kerebos authentication.  Any advice?


Thank You
