Hello, I have been running the below c# code snippet with the .net client SDK (version 5.1.0) against our Lightstreamer server version 7.2.2 and I kept getting invalid handshake and the connection kept switching to HTTP.
I tried ForcedTransport = "WS" and "WS-Streaming" as well but still no luck.
I tried the quickstart example on here, https://sdk.lightstreamer.com/ls-dotnetstandard-client/6.0.0/api/articles/intro.html and it worked fine with me.
Also I have a Java version (similar to the C# code below) and it works fine as well. It connects and I get status WS-Streaming back successfully. Somehow I can't make it work with the following though. Any idea what could be the reason?
using com.lightstreamer.client;
using Lightstreamer.DotNet.Logging.Log;
namespace ConsoleApp;
internal class Program
{
public static void Main()
{
LightstreamerClient.setLoggerProvider(new Log4NetLoggerProviderWrapper());
var client = new LightstreamerClient("https://myurl", "myAdapterSet")
{
connectionDetails =
{
User = "user",
Password = "token"
}
};
}
}
Log;
