RTD Demo will not connect to Lightstreamer Server

[lxnay]

krohnjw,
to me, there might be two reasons:

- the most obvious: connectivity issues (firewall with DROP policy, etc) that make the UI freeze (UI thread is the same of Excel RTD thread, at the moment)
- more sneaky: an uncaught exception is generated at:

new ThreadStart(delegate() { lsClient.Start(pushServerUrl); }).Invoke();

Try to replace it with something like:

new ThreadStart(delegate() { try { lsClient.Start(pushServerUrl); } catch (Exception e) { flowForm.AppendExcelLog(e.Message); }; }).Invoke();

No exception thrown - continues to hang and excel eventually thows an alert that it's waiting for an OLE operation to complete.

- the most obvious: connectivity issues (firewall with DROP policy, etc) that make the UI freeze (UI thread is the same of Excel RTD thread, at the moment)

Again, there is no firewall up and running. I can connect to both servers without a problem via the javascript library from this machine (Win 7 64 bit). If I run a ping or connect via HTTP I see the traffic fine in wireshark. However, with the RTD demo I continue to see not a single packet headed to the server.

Is there a significant difference in how this connects from the javascript library that would allow it to work fine using HTTP/Javascript but the connect from the .NET environment would fail?

The Javascript library is different from the .NET library, but the way they use the network is the same.
If, using wireshark, you don't see anything on the NIC while the RTD app loads and tries to connect, this, would make me think that there is some local application that is blocking the outgoing packets. Even if it wouldn't explain why everything works with push.lightstreamer.com.
Could you double check that there is no local firewall even? (Windows Firewall? Try to turn it off just in case).
At the same time, could you, through support@lightstreamer.com provide us some valid credentials that we can use to connect to your server through the RTD library, if possible?

Regards.

Already done - both the Windows firewall and all 3 party products have been disabled for the duration of testing.

Thanks,
at my first attempt, the application is able to connect and communicate with your server. I have a further request though, could you send us the Excel file you're using?

Well, that's good news. Sent as requested.

I confirm. With the information you gave us, I am able to communicate with your server, which just answers: "Requested Adapter Set not available", which confirms that the communication is successful, without blocking the UI.
