.NET SDK - error connecting to QlikSense through certificate

master_t — Fri, 06 Apr 2018 10:49:40 GMT

Hello

I'm trying to use the .NET SDK to connect to a QlikSense server (febbruary 2018 version) using a certificate.

I exported the certificate from the QMC (including private key) and then I try to use this code:

Uri uri = new Uri("https://mysenseserver.local");
var senseLocation = Qlik.Engine.Location.FromUri(uri);


//Load certificate
X509Certificate2 x509 = new X509Certificate2(@"C:\client.pfx", "cert_password", X509KeyStorageFlags.UserKeySet);
X509Certificate2Collection x509coll = new X509Certificate2Collection(x509);


//Connect to QlikSense server
senseLocation.AsDirectConnection(
    "myuserdir", //User directory
    "administrator", //UserID (this user is RootAdmin)
    false,
    false,
    x509coll //Certificate
);


//Connect to app
var appIdentifiers = senseLocation.GetAppIdentifiers(); //This causes exception...

this causes the following exception:

GeneralCommunicationException with communication error WebSocketClosed and http error code 500

   at Qlik.Engine.Communication.QlikConnection.AwaitResponseTask(T task, String methodName, CancellationToken cancellationToken)

   at Qlik.Engine.Communication.QlikConnection.Ping(Nullable`1 noVersionCheck)

   at Qlik.Engine.LocationExtensions.Hub(ILocation location, ISession session, Nullable`1 noVersionCheck)

   at Qlik.Engine.LocationExtensions.GetAppIdentifiers(ILocation location, Nullable`1 noVersionCheck)

   at QlikExporter.Core.Logic.SenseAgent.ConnectToApp()

can anyone tell me what I'm doing wrong?

If you do a direct connection, then you should typically add the Engine port number to the Uri. Default value for this is 4747 for a Server installation of Qlik Sense (4848 for desktop). Check out this example:

Thanks, that was the issue! Port 4747 is working correctly.
