I have the following code for connection to my websocket, but the problem is when the domain has an SSL certificate as it is my case, when I make the connection with ws everything works perfectly, but when I put the wss I get this error
Error in connection establishment: net::ERR_SSL_PROTOCOL_ERROR
index.js
<script type="text/javascript">
$(document).ready(function(){
//create a new WebSocket object.
var wsUri = "wss://dominio.com:9001/socket.php";

websocket.onopen = function(ev) { // connection is open
var preg = {
id: 303,
historial: {

};
//convert and send data to server
websocket.send(JSON.stringify(preg));
}
//#### Message received from server?
