stream error

[manuks]

I am calling readTcpStream as below

  $streamReader = new StreamReader();
  foreach ($streamReader->readTcpStream($lineReader, "127.0.0.1", 30003) as $line) {
  //some code here
  }

But I am getting the error like below
local.ERROR: RuntimeException: Unexpected stream error in /var/www/html/vendor/afk11/sbs1/src/StreamReader.php:97

Any idea how to fix this?
