function init() { var host = "ws://XX.XX.XXX.XXX:XXXX"; // SET THIS TO YOUR SERVER try { var socket = new WebSocket(host); // alert('WebSocket - status ' + socket.readyState); log('WebSocket - status ' + socket.readyState); socket.onopen = function (msg) { alert('open'); alert("Welcome - status " + this.readyState); log("Welcome - status " + this.readyState); if (this.readyState != 1) { reconnect(); } }; socket.onmessage = function (msg) { // alert("Received: " + msg.data); log("Received: " + msg.data); }; socket.onclose = function (msg) { // alert("Disconnected - status " + this.readyState); log("Disconnected - status " + this.readyState); }; } catch (ex) { alert(ex); log(ex); } $("msg").focus(); } |

Firefox can't establish a connection to the server at ws://XX.XX.XXX.XXX:XXXX. var socket = new WebSocket(host); |
Answer:
I’d try your code and for me is working just fine, I’d test it with this webpage: https://www.websocket.org/echo.html , maybe could be helpful for testing purposes. But also i found this question: websocket-rails, websocket handshake error , maybe also help.
However i’d just change the host in your code to this:”ws://echo.websocket.org”, and everything works without problems.
Hope you find a solution and that this info was of any help. Here’s your code that i used for the test:
