Why cant I connect outside?

[xoid]

I added this code
function button(who, state)
{
console.log(‘button:’);
var xhr = new XMLHttpRequest();
var body = 'who ’ + who + "\nstate " + state;
xhr.open(“POST”, ’http://192.168.171.1/submit', true);
xhr.setRequestHeader(‘Content-Type’, ‘application/x-www-form-urlencoded’);
xhr.send(body);
}

for onclick of a simple button. It works fine in browser, why it dont work in Monaco IDE ?
All I see in console log is
button:
try - catch dosnt catch any errors too
