SFTP PHP 5.6 using phpseclib hangs

Question

I'm trying a simple example

$sftp = new phpseclib\Net\SFTP(FTP_ADDRESS);
if (!$sftp->login(FTP_USER, FTP_PASS)) {
    $logger->error("FTP credentials error");
    $logger->error($sftp->getLastSFTPError());
} else {
    $logger->log("Connection successful");
}

  print_r($sftp->rawlist());

However the script just hangs and finally times out

( ! ) Fatal error: Maximum execution time of 30 seconds exceeded in C:\xampp\htdocs\XookCatalogFeed\lib\phpseclib\Net\SSH2.php on line 3186

I have tried a lot of stuff but nothing seems to work. I have done some debugging (step by step) it looks like the servers accepts thje credential but then the client just loops sending empty data at _send_binary_packet.

Here is the log: https://gist.github.com/vlopez/2a48d261ab7713dbc06d

Someone, please help.
