Can't connect to anything - System.Net.Sockets.SocketException

[TheWrightDev]

I feel like there is a simple explanation and I'm doing something dumb here. But I'm just trying to setup a basic ws connection, my code looks like:

using (var ws = new WebSocket("ws://localhost:4444/"))
{
    ws.Log.Level = LogLevel.Trace;
    ws.OnMessage += (sender, e) => Console.WriteLine("ws says: " + e.Data);
    ws.Connect();
}

The output I get is:

3/31/2022 4:00:45 PM|Warn |Logger.set_Level|The current logging level has been changed to Trace.
3/31/2022 4:00:45 PM|Fatal|WebSocket.connect|The operation completed successfully.

Disconnected to websocket server.

I can connect to it fine with the same address using basic System.Net.WebSockets library and the ClientWebSocket class. But websocket-sharp just gives that error and bails out no matter what I seem to change.

CMIIW, isn't that the problem with the websocket server?

I tried to do the same thing as yours I'm using .NetFramework 4.8 And my websocket server is https://www.piesocket.com/websocket-tester# However, there are no problem happened as you mention above

I've the same issue, I am able to connect with websocket server, but WebSocket method doesn't work and gives the same error
