I am having a problem where my Flex application dipplays this error:

Code:
faultCode:Server.Error.Request faultString:'HTTP request error' faultDetail:'Error: [IOErrorEvent type="ioError" bubbles=false cancelable=false eventPhase=2 text="Error #2032: Stream Error.
Error is displayed every time i use HTTPService for connecting to a simple .php script:

PHP Code:
<?php

include('file_handler.php');

$f = new file_handler("server", 80, "username", "password", "url", WEBDAV);

?>
I should mention that .php script work just fine when executed directly from browser and basically what it does is connect to a remote server using webdav protocol through custom 'file_handler.php' class. If i remove the line:

Code:
$f = new file_handler("webct.carnet.hr", 80, "username", "password", "url", WEBDAV);
used for connecting error is not displayed. I googled and didn't find any solution and what's even worse i don't know what's the problem? Can someone help me on this?
