Soap: <faultstring> 11|Session|</faultstring> - php

Question

I am getting faultcode error with soap as per below while using soap request with php.
<soap:Body><soap:Fault><faultcode>soap:Client</faultcode><faultstring> 11|Session|</faultstring></soap:Fault></soap:Body>
Kindly suggest about this error.
I am using below code in PHP :
$request = '<soapenv:Envelope xmlns:soapenv="..>
<soapenv:Header xmlns:add="http://www.w3.org/2005/08/addressing">
<MessageID>...
<oas:Security xmlns:..">
<oas:UsernameToken oas1:Id="UsernameToken-1">
...
</oas:UsernameToken>
</oas:Security>
<awsse:Session TransactionStatusCode="Start" xmlns:awsse="http://xml.amadeus.com/2010/06/Session_v3"/>
</soapenv:Header>
<soapenv:Body>
....
</soapenv:Body>
</soapenv:Envelope>';
$soapaction = "..";
$url = "..";
$headers = array(
"Accept-Encoding: gzip,deflate",
"Content-Type: text/xml;charset=UTF-8",
"SOAPAction: $soapaction",
"Connection: Keep-Alive",
"Host: nodeD1.test.com",
"User-Agent: ".$_SERVER['HTTP_USER_AGENT'],
"Content-length: ".strlen($request)
);
$ch = curl_init();
curl_setopt($ch, CURLOPT_SSL_VERIFYPEER, 0);
curl_setopt($ch, CURLOPT_URL, $url);
curl_setopt($ch, CURLOPT_RETURNTRANSFER, true);
curl_setopt($ch, CURLOPT_POST, true);
curl_setopt($ch, CURLOPT_POSTFIELDS, $request);
curl_setopt($ch, CURLOPT_HTTPHEADER, $headers);
curl_setopt($ch, CURLOPT_ENCODING, 1);
curl_setopt($ch, CURLOPT_HEADER, false);
$response = curl_exec($ch);
I have tried with $client->__doRequest method with SoapClient class.

Usually this causes from authentication issue. The request which you constructed could not reach the resources on target because of incorrect authentication or header data. please try this it will work.
-You should check all parameters in <soapenv:Header>.
-Username in the UserToken might be missing or incorrect.
