Need help with plane game

Hi guys,

First time poster here, I am making a flying plane game with a scrolling background (1920x1080), there is also a banner at the top with some stats. I want to be able to have it in my game as a (800x600) and then have a camera that follows the position of the plane in relation with the screen. 

When I use game.camera.follow(plane); it doesn't work and traps the screen in the top left of the screen.

Here is some code for context:

var game = new Phaser.Game(800, 600, Phaser.CANVAS, '', { preload: preload, create: create, update: update, render: render });

function preload() {

    ///Load assets
    game.load.image('sky', 'assets/backplate2.png');
    game.load.image('plane', 'assets/plane.png');
    game.load.image('banner', 'assets/screenbanner.png');

}

var backgrounda = 0.1;
var backgroundv = 2;
var width;
var height;
var energy = 0;
var scoreText;

function create() {

    sky = game.add.tileSprite(0, 0, 1920, 1200, 'sky');
    banner = game.add.sprite(0, 0, 'banner');
    player = game.add.sprite(500, 500, 'plane');
    scoreText = game.add.text(16, 16, 'Energy:  0 J', { fontSize: '32px', fill: '#229'});

    game.physics.startSystem(Phaser.Physics.arcade);

    game.physics.arcade.setBounds(0, 70, 1920, 960);

    game.physics.arcade.enable(player);
    game.camera.follow(player);

    banner.scale.setTo(0.42, 0.42);
    player.scale.setTo(0.1, 0.1);
    player.body.gravity.y = 400;
    player.body.collideWorldBounds = true;

    cursors = game.input.keyboard.createCursorKeys();

}

function update() {

    sky.tilePosition.x -= Math.min(backgroundv + backgrounda, 100);
    player.body.velocity.x = 0;

    if (cursors.left.isDown)
    {
        player.body.velocity.x = -150;
        player.animations.play('left');
    }
    else if (cursors.right.isDown)
    {
        player.body.velocity.x = 150;
        player.animations.play('right');
    }
    else
    {
        player.animations.stop();
        player.frame = 4;
    }

    if (cursors.up.isDown)
    {
        player.body.velocity.y = -300;
        backgroundv = (backgroundv + backgrounda);
        player.body.rotation = (Math.max(-20, player.body.rotation-1));
        energy += 2;
        Math.round(energy);
        scoreText.text = 'Energy:  ' + energy + ' J';
    }
    else if (cursors.down.isDown)
    {
        backgroundv = backgroundv - (backgrounda/2);
        backgroundv = Math.max(backgroundv, 0) - (backgrounda/2);
        player.body.rotation = (Math.min(0, player.body.rotation+1));
    }

    //else {
        //backgroundv = backgroundv - backgrounda;
        //backgroundv = (Math.max(backgroundv, 0) - backgrounda);
    //} 

}

function render() {
    game.debug.cameraInfo(game.camera, 32, 32);
    game.debug.spriteCoords(player, 32, 500);
}
