Research direction

Start with the Connection.cs sample shown in the report and trace its connection setup for ws://localhost:3000. Check the expected server and runtime context against the reported error, then verify the sample can establish a connection without the remote-server failure.

Description

`
public class WebSocketController : MonoBehaviour
{
WebSocket websocket;

    // Start is called before the first frame update
    async void Start()
    {
        websocket = new WebSocket("ws://localhost:3000");

        websocket.OnOpen += () =>
        {
            Debug.Log("Connection open!");
        };

        websocket.OnError += (e) =>
        {
            Debug.Log("Error! " + e);
        };

        websocket.OnClose += (e) =>
        {
            Debug.Log("Connection closed!");
        };

        websocket.OnMessage += (bytes) =>
        {
            Debug.Log("OnMessage!");
            Debug.Log(bytes);

            // getting the message as a string
            // var message = System.Text.Encoding.UTF8.GetString(bytes);
            // Debug.Log("OnMessage! " + message);
        };

        // Keep sending messages at every 0.3s
        InvokeRepeating("SendWebSocketMessage", 0.0f, 0.3f);

        // waiting for messages
        await websocket.Connect();
    }

    void Update()
    {

#if !UNITY_WEBGL || UNITY_EDITOR
websocket.DispatchMessageQueue();
#endif
}

    async void SendWebSocketMessage()
    {
        if (websocket.State == WebSocketState.Open)
        {
            // Sending bytes
            await websocket.Send(new byte[] { 10, 20, 30 });

            // Sending plain text
            await websocket.SendText("plain text message");
        }
    }

    private async void OnApplicationQuit()
    {
        await websocket.Close();
    }
}
