xml-rpc telling me I don't have permission to post

Ever since wp changed to https my xmlrpc posting is broken.

So I am trying to use xmlrpc within wordpress and kept getting malformed xmlrpc message. After a few tries, I guess the automatic xmlrpc.php protection kicked in and now I’m getting a message ‘Sorry, you are not allowed to post on this site.’

The site I’m posting FROM is a self-hosted wp site
The site I’m posting TO is https://factorstreetpaper.wordpress.com/

Question #1: How do I regain my ability to post to the wordpress.com xmlrpc.php?

Question #2: What the heck is wrong with the code below that it thinks my request is incorrect?

$client = new WP_HTTP_IXR_CLIENT("https://factorstreetpaper.wordpress.com/ );
	$bSuccess = $client->query( 'wp.newPost',
		array(
			0,
			$sUsername,
			$sPassword,
			array(
				'post_status'  => 'draft',
				'post_type'  =>'post',
				'post_title'   => "Karen test",
				'post_content' => "test post"
			)
		)
	);

	if(!$bSuccess){
            print "Error msg from XMLRPC =". $client->error->message."<br />";
}
