lost connect to stompEndPoint

[mastershashi]

Hi ,

For me Socket JS is unable to make a connection with the server in cloud foundry .
here is my code
var socket = new SockJS('/websocket-example');
stompClient = Stomp.over(socket);
stompClient.connect({}, function (frame) {
setConnected(true);
console.log('Connected: ' + frame);
showGreeting("Connected");
stompClient.send("/app/user", {}, JSON.stringify({'name': $("#name").val()}));
if (stompClient !== null) {
stompClient.disconnect();
}
setConnected(false);
console.log("Disconnected");
});

In Localhost it is working fine but in in cloud foundry it is not working it unable to establish the connection
Log:

Can you please tell me what could be the possible reason for this ?

Hi mastershashi,
I can just point a couple of directions.
Please check out how the WAR got deployed on websocket-cf.cfapps.sap.hana.ondemand.com. Can it be that the context /websocket-example differs? May be the app was deployed this way: https://websocket-cf.cfapps.sap.hana.ondemand.com/info?t=1536215752774 - with empty context?
Or with additional level in context, say https://websocket-cf.cfapps.sap.hana.ondemand.com/my_apps/websocket-example/info?t=1536215752774
Was the app deployed on port 80? Maybe you need to specify a port explicitly?
Are there any access restrictions on the cloud? Is port 8080 open?
And the common advice: search for the difference between localhost and cloud deployments.
