❔ WebSocketSharp and Azure Endpoint (Error 1006)

Summary: 1) I create a UnityWebRequest which is used to call request.SendWebRequest(). 2) Use the returned request.downloadHandler.text to create a ws = new WebSocket(request.downloadHandler.text, "json.webpubsub.azure.v1"); 3) Attempt to perform ws.Connect() However, ws.Connect() never connects and instead always triggers OnClose() instead, citing error 1006. My actual code:

   private IEnumerator ConnectToAzure()
    {
        string url = "https://myurl.azurewebsites.net/api/createprivatemessage?code=mycode";

        InputData inputData = new InputData { sender = playFabId };
        string data = JsonConvert.SerializeObject(inputData);
        UnityWebRequest request = new UnityWebRequest(url, "POST");
        byte[] bodyRaw = Encoding.UTF8.GetBytes(data);
        request.uploadHandler = (UploadHandler)new UploadHandlerRaw(bodyRaw);
        request.downloadHandler = (DownloadHandler)new DownloadHandlerBuffer();
        request.SetRequestHeader("Content-Type", "application/json");

        yield return request.SendWebRequest();

        if (request.result == UnityWebRequest.Result.ConnectionError || request.result == UnityWebRequest.Result.ProtocolError)
        {
            Debug.LogError(request.error);
        }
        else
        {
            ws = new WebSocket(request.downloadHandler.text, "json.webpubsub.azure.v1");
            IsWebSocketUrlReachable(url);
            // Set the WebSocket headers
            // client.SetCredentials(azureConnection, "", false);
            ws.OnOpen += OnWebSocketOpen;
            ws.OnMessage += OnMessage;
            ws.OnError += OnError;
            ws.OnClose += OnClose;
            ws.Connect();
            if(ws.ReadyState!= WebSocketState.Open) {
                Debug.Log("WebSocket was NOT opened. Something went wrong during initial connection in ConnectToAzure()");
            }
        }
        request.Dispose();
    }

   private IEnumerator ConnectToAzure()
    {
        string url = "https://myurl.azurewebsites.net/api/createprivatemessage?code=mycode";

        InputData inputData = new InputData { sender = playFabId };
        string data = JsonConvert.SerializeObject(inputData);
        UnityWebRequest request = new UnityWebRequest(url, "POST");
        byte[] bodyRaw = Encoding.UTF8.GetBytes(data);
        request.uploadHandler = (UploadHandler)new UploadHandlerRaw(bodyRaw);
        request.downloadHandler = (DownloadHandler)new DownloadHandlerBuffer();
        request.SetRequestHeader("Content-Type", "application/json");

        yield return request.SendWebRequest();

        if (request.result == UnityWebRequest.Result.ConnectionError || request.result == UnityWebRequest.Result.ProtocolError)
        {
            Debug.LogError(request.error);
        }
        else
        {
            ws = new WebSocket(request.downloadHandler.text, "json.webpubsub.azure.v1");
            IsWebSocketUrlReachable(url);
            // Set the WebSocket headers
            // client.SetCredentials(azureConnection, "", false);
            ws.OnOpen += OnWebSocketOpen;
            ws.OnMessage += OnMessage;
            ws.OnError += OnError;
            ws.OnClose += OnClose;
            ws.Connect();
            if(ws.ReadyState!= WebSocketState.Open) {
                Debug.Log("WebSocket was NOT opened. Something went wrong during initial connection in ConnectToAzure()");
            }
        }
        request.Dispose();
    }

I am new to azure. How can I debug?

IsWebSocketUrlReachable(url); is a ping function I implemented to test the reachability of the ws address. It always returns true, which further mystifies me.

   public bool IsWebSocketUrlReachable(string url) {
        try {
            Uri uri = new Uri(url);
            string host = uri.Host;

            using (Ping ping = new Ping()) {    //use SystemNetworkingInformation Ping (not Unit's object)
                PingReply reply = ping.Send(host);

                if (reply.Status == IPStatus.Success) {
                    Debug.Log("Can reach the WebSocket server!");
                    return true;
                }
                else {
                    Debug.Log("CANNOT reach the WebSocket server!");
                    return false;
                }
            }
        }
        catch (Exception) {
            // An exception occurred (e.g., invalid URL)
            return false;
        }
    }

   public bool IsWebSocketUrlReachable(string url) {
        try {
            Uri uri = new Uri(url);
            string host = uri.Host;

            using (Ping ping = new Ping()) {    //use SystemNetworkingInformation Ping (not Unit's object)
                PingReply reply = ping.Send(host);

                if (reply.Status == IPStatus.Success) {
                    Debug.Log("Can reach the WebSocket server!");
                    return true;
                }
                else {
                    Debug.Log("CANNOT reach the WebSocket server!");
                    return false;
                }
            }
        }
        catch (Exception) {
            // An exception occurred (e.g., invalid URL)
            return false;
        }
    }

Looks like nothing has happened here. I will mark this as stale and this post will be archived until there is new activity.
