i'm using the qlik sense .net api to connect to an existing/open qlik sense app and select some field values. Example code:
qLoc = Qlik.Engine.Location.FromUri("https://qsserver/hub:443");
qLoc.AsNtlmUserViaProxyAsync(true, null, false).Wait();
qAppId = Qlik.Engine.LocationExtensions.AppWithId(qLoc, "guid", true);
qSession = Qlik.Engine.Session.WithApp(qAppId, Qlik.Engine.SessionType.Default);
qApp = Qlik.Engine.LocationExtensions.App(qLoc, qAppId, qSession, true, false);
qField = qApp.GetField("fieldname", "");
qField.Select("value", true, 0);
This works most of the time, but sometimes an exception is thrown in the 3. line (AppWithId-call):
"System.IO.IOException: Unable to read data from the transport connection : An existing connection was forcibly closed by the remote host"
Second /inner exception:
"System.Net.Sockets.SocketException: An existing connection was forcibly closed by the remote host"
What could possibly cause these exceptions? Is this perhaps a known problem?
