I am trying to make my first transaction and I am failing. I try using private and public node. If I use :

var iota = new IOTA({
   'provider': ' https://nodes.thetangle.org:443'
});
 
var seed = 'AAA....';
var address = 'xyz....';

 
var messageToSend = {
    'name': 'Dominik',
    'message': 'My first message sent with IOTA.'
}


var messageStringified = JSON.stringify(messageToSend);

var messageTrytes = iota.utils.toTrytes(messageStringified);

var transfer = [{
    'address': address,
    'value': 0,
    'message': messageTrytes
}];

iota.api.sendTransfer(seed, 4, 18, transfer, function(e, bundle) {
    if (e) throw e;
    console.log("Successfully sent your transfer: ", bundle);
});

I get

Error: Request Error: Couldn't get a response from nodes

if I connect to my private node instead

 var iota = new IOTA({
'host': 'http://xx.xxx.xxx.x',
'port': 14700

});

I am waiting forever. Any idea what am I doing wrong?
