after installing amfphp 1.9 package in my server and opening the browser folder,the application saw me the error

errorID = 0
faultCode = “Client.Error.MessageSend”
faultDetail = “Channel.Connect.Failed error NetConnection.Call.Failed: HTTP: Failed”
faultString = “Send failed”
message = “faultCode:Client.Error.MessageSend faultString:‘Send failed’ faultDetail:‘Channel.Connect.Failed error NetConnection.Call.Failed: HTTP: Failed’”
name = “Error”
rootCause = (Object)#1
code = “NetConnection.Call.Failed”
description = “HTTP: Failed”
details = “http://www.myserver.com/amfphp/gateway.php
level = “error”
i have been googling from 3 days .
Every body has stated the problem but no answer.

Please help me to correctly install the amfphp package.

Thanks in advance.
