I am trying to connect to SFTP server. Here is the code :

  set_include_path(get_include_path() . PATH_SEPARATOR . 'phpseclib');
  require_once('Crypt/RSA.php');
  require_once('Net/SSH2.php');
  require_once('Net/SFTP.php');
  $ssh = new Net_SFTP('some.server.com', '22000');
  if (!$ssh->login('my_login', 'my_password')) {
     $log->lwrite('SSh Login Failed');
  }
  $dir = "output/";
  $files = glob($dir . "*.*");

  foreach($files as $file)
  {
    $fileName = substr($file,strrpos($file,"/")+1);
    if (substr($file,-4) == ".asc"){
        $output = $ssh->put('dir/'.$fileName,$file,FTP_ASCII); // FTP_BINARY
    }
  }

I'm 100 percent sure, that the host, password and login is correct. Because I can access the server with this input through WinSCP. However this is the response I get:

Notice: Unable to request pseudo-terminal in ***/Net/SSH2.php on line 2195

Notice: Connection closed prematurely in ***/Net/SSH2.php on line 2303

This is the first time I ever encountered a notice like this. I've already tried to find the answer here, but I found nothing so I had to ask.

Btw every 2-30 seconds sftp server disconnects me when I'm connected through WinSCP with error :

Network error: Software caused connection abort

I can say from log, that I get

NET_SSH2_MSG_USERAUTH_SUCCESS

also

NET_SSH2_MSG_CHANNEL_OPEN_CONFIRMATION and NET_SSH2_MSG_CHANNEL_EXTENDED_DATA

after which it says Welcome message (local time, experimental ftp server and so on). But after that I get:

NET_SSH2_MSG_DISCONNECT

So please, can anybody tell me why does this happen? Thank you in advance :-)

P.S: I have no control of the sftp server that I'm trying to connect to.

EDIT:

This is the line that is causing the problem :

!$ssh->login('my_login', 'my_password')

And as i said: login, host, port and password are 100% correct.

EDIT2: extracted log
