xmlrpc request object error 32300 transport error

Question

    $postcontent = array(
        'post_type' => 'post',
        'post_status' => $post_status, 
        'post_title' => $post_title,
        'post_name' => $post_title,
        'post_content' => $post_content,

        'post_thumbnail' => $image_returnInfo['id']
    //  'terms_names'=> array( 'category' => $category_battery),

    );

$res = $client -> query('wp.newPost',1, $usr, $pwd, $postcontent);
$postID =  $client->getResponse();

print_r($client); 

While i tried to insert the post from xmlrpc wordpress api i got error 32300. How can i solve this?

i got following result.

IXR_Client Object

Please follow this link (https://codex.wordpress.org/XML-RPC_WordPress_API). Changing the port might help because all the ports take default value 80. Changing it into port number into 81 or other numbers might help.
