The easiest (and generally correct) solution is to use an FTP passive mode, instead of an active mode (the default in PHP).

W3tc use active mode see: https://github.com/szepeviktor/w3-total-cache-fixed/blob/b225070f2c68b45411cb8ba69d2c007627909678/CdnEngine_Ftp.php

	/**
	 * PHP5 Constructor
	 *
	 * @param array   $config
	 */
	function __construct( $config = array() ) {
		$config = array_merge( array(
				'host' => '',
				'type' => '',
				'user' => '',
				'pass' => '',
				'path' => '',
				'pasv' => false,
				'domain' => array(),
				'docroot' => ''
			), $config );
		$host_port = explode( ':', $config['host'] );
		if ( sizeof( $host_port ) == 2 ) {
			$config['host'] = $host_port[0];
			$config['port'] = $host_port[1];
		}
		parent::__construct( $config );
	}

Try to change
‘pasv’ => false
With
‘pasv’ => true
