Bug: Can't Establish Websocket from html webpage about magistrala HOT 8 CLOSED

Hello @andychao217. Please fill in the issue template properly. However, from the log you shared, it seems you are not using the correct Thing key for the authorization. Please check docs: https://docs.magistrala.abstractmachines.fr/messaging/#websocket. Also, when sharing code snippets, please share them as code block so we can easily reproduce and copy things for debugging.

      var secret = "{{.Entity.Credentials.Secret}}";
        function setupWebSocket() {
          let ws = null;
          function connect() {
            const channelId = "91b2957b-fabd-45f9-8ec0-1509028426bc";
	          const socketUrl = "ws://192.168.1.151:8186/ws/channels/" + channelId + "/messages?authorization=" + secret
            const ws = new WebSocket(socketUrl);
            ws.onopen = function(event) {
              console.log('WebSocket connected');
            };
            ws.onclose = function(event) {
              console.log('WebSocket disconnected');
              setTimeout(connect, 1000);
            };
            ws.onerror = function(error) {
              console.error('WebSocket error observed:', error);
            };
            ws.onmessage = function(event) {
              console.log('Message from server:', event.data);
            };
          }
          connect(); 
        }
        setupWebSocket();

am i writing the correct code ?

It depends on what's the secret value. From the log, it looks like it's 12345678-2 which is a wrong Thing key format and probably a wrong Thing Key. The code otherwise looks OK.

Also, please check the URL. Looks like you are using both prefix and port, try ws://localhost:8186/channels/ or ws://localhost/ws/channels/.

i tried both ways, but still can't establish the connection

Can you try using Postman or some other tool that is not running from the browser?
