Connect on a different url?

I have an angularjs app running on port 3131. This is what I get in the console.

```
GET XHR http://127.0.0.1:3131/socket.io/ [HTTP/1.1 404 Not Found 2ms]
"
Socket is trying to reconnect to Sails...
_-|>_- (attempt #4)

"
```

So I've tried to change the url but the output stayed the same

```
io.sails.url = 'http://localhost:1337';
```

Is there a way to achieve this?

Thank you
