Power Shell script for open port check doesn't work properly

Hi,

I have a problem with PS script that is checking if port on remote host is open or not. I'm executing this script with Custom EXE/Script sensor and it is working but always giving the 1:ERROR value, below you will find the code :

try

{
 
  $tcp=new-object System.Net.Sockets.TcpClient 

  $tcp.connect("10.10.10.10",445)
 
 Write-Host "0:OK"
 
 $tcp.close() 

} 

catch 

{ 

  Write-Host "1:ERROR"

}

Script is working fine with "Invoke command" from Powershell console and its giving the correct value.

Someone ?
