I was able to get a demo working using the Lightstreamer quickstart C# example.

I am trying to integrate this demo with the Gain Capital streaming adapter.

I am working with Lightstreamer.DotNetStandard.Client (5.0.5) and I instantiated and populated a LightstreamerClient object so it looks like this:

The value I used for the password was the session token I got from https://ciapi.cityindex.com/TradingAPI/session (as the documentation states) and the User is the username that was given to me for the demo account.

When I try run the Connect() method on my LightstreamerClient object, this is what I get:


I can't find documentation for this error anywhere. Do you know what I am doing wrong?

Thanks in advance,
