NetStream Not Working - S3 - Cloudfront - signed files

Hello,

I have amazon cloud front on S3. I have valid rtmp link as it works in VLC.

Can you help me make it work?

I use AIR18

Here is the code

public function Main() {

   url = "rtmp://s1p2w2yhnipjkt.cloudfront.net/cfx/st/mp4:demo.mp4?Expires=1594281188&Signature=AW0 M39xRqX5bjhlw4EPMvdPzum8~gbK6Wsl7vkI3av6cWDXQ36lCfTlnpOXse6qiP9RSbuT-jhor84DHvZg7yPmvnnlPg AEQlndtgsBvzwUj~kGXES~~VWvHGVuUHTDnK~rAWcOmzpbRi-jWPpN71Ks2wnJeri596lqh2dOkUcg_&Key-Pair-I d=APKAI7XWAS4L22TVE3HA";

   _netConnection = new NetConnection();
   _netConnection.addEventListener(NetStatusEvent.NET_STATUS, onConnect);
   _netConnection.client = {onBWDone:onNetConnectionBWDone};


   _netConnection.connect(url);
  //` _netConnection.connect("rtmp://s1p2w2yhnipjkt.cloudfront.net/cfx/st");

   trace("connect")

I tried both connecting to signed url and just to application. It never came to onConnect

  }

   private function onConnect(event:NetStatusEvent):void {

   trace(event.info.code);
   if(event.info.code == "NetConnection.Connect.Success")

  {

   _netStream = new NetStream(_netConnection);
   _netStream.client = {onMetaData:onMetaData, onPlayStatus :onPlayStatus};
   var video:Video = new Video();
   video.attachNetStream(_netStream)

_netStream.play("mp4:demo.mp4?");
   addChild(video);

   }

  }

private function onNetConnectionBWDone():void{}

// NetStream Status handlers

   private function onMetaData(o:Object):void{}

   private function onPlayStatus(o:Object):void{}
