Connecting to Qlik sense Server using .NET SDK

[#1]

Hi,

I am using qlik sense server version 2.1.1 and have .net sdk version also 2.1.1. I am trying to build a windows forms application which simply displays the server version. When I run the code, it gives me an error "unable to keep connection opened".

I am attaching the screenshot of error and below is my code.

     private void Form1_Load(object sender, EventArgs e)

        {          

            Uri uri = new Uri("https://abdullah-pc:4747");  // abdullah-pc is my server machine

            ILocation location = Qlik.Engine.Location.FromUri(uri);

            location.AsNtlmUserViaProxy();

            using (IHub hub = location.Hub())

            {

                label1.Text = hub.ProductVersion();

            }

        }

If anyone helps, I'll be thankful.

Hi,

are you running with the proxy? If so have you configured "Websocket origin white list" in your qmc (see Virtual proxies - Advanced), you can add your ip-adress or your domain (for example qlik.com).

It could also be issues with your certificate configuration, you can test to allow HTTP (see Proxies - Ports),

in this case you should use http://abdullah-pc

Hi Kolsurd,

I have tried this already as I have said. And I can see my user directory in manage resources under qmc. But still I am unable to achieve server version. Same error is popped out.

Also can you help me with manual reload a specific task or app in server, from aspx page using .net sdk or any other API.

Will be thankful,

Abdul Rahman

Hi,

I can see that you are using the port for the engine but when connecting you going to the proxy.

There should not be any port in the uri when connecting thru the proxy i.e.

Uri uri = new Uri("https://abdullah-pc");
