IStreamingListener.Start() hangs for indefinite time

[Guest andreif]

I’m trying to subscribe for news stream (using WPF), and the sample code hangs on IStreamingListener.Start() call for some indefinite time. (I waited 5 mins). Nothing seem to happen, and only debug output shows this message from time to time:

A first chance exception of type ‘Lightstreamer.DotNet.Client.PushLengthException’ occurred in StreamingClient.Lightstreamer.dll

Stack trace:

Exception is thrown one line upper this string:

if (extraMsg.StartsWith(“END”))

error message is “Connection consumed”

UPD this problem happens, when using http (not https) streaming URL.
UPD2 surprisingly, the same code works with Silverlight version (using http) and accepts newsfeeds correctly

You can use code from the Example.FetchNews sample. Just replace https with http.
