DHL, PHP SOAP rate implementation not working - php

Question

You are my last hope!
I'm trying to implement DHL'S rating API to a website.
They send to me the sample code, I tried it to the demo environment with demo credentials and it worked fine.
Later they change the endpoint url and send to me the permanent credentials.
After that I can't make it to work. I'm getting the following error:
SOAP Fault!
FaultCode: WSDL FaultString: SOAP-ERROR: Parsing WSDL: Couldn't load
from 'https://wsbexpress.dhl.com:443/gbl/expressRateBook' : failed to
load external entity
My PHP code goes like this:
<?php
// The url of the service
$url='https://wsbexpress.dhl.com:443/gbl/expressRateBook';
// the soap operation which is called
$action='euExpressRateBook_providerServices_ShipmentHandlingServices_Binder_getRateRequest';
// the xml input of the service

echo "FaultString: {$output->faultstring} <br/>";
}else{
echo("<h2>Output: </h2><p>");
echo $output;
echo("</p/>");
}
?>
Where ********* my actual credentials.
If I give as endpoint url
https://wsbexpress.dhl.com/gbl/expressRateBook?wsdl
I'm getting as response the SOAP schema.
Could you help to find out whats wrong and I'm no getting the right response?

Try to experiment with options like this:
$opts = array(
'ssl' => array(
'verify_peer' => false,
'verify_peer_name' => false,
'allow_self_signed' => true
)
);
$options = array (
'encoding' => 'UTF-8',
'verifypeer' => false,
'verifyhost' => false,
'soap_version' => SOAP_1_2,
'trace' => 1,
'exceptions' => 1,
'connection_timeout' => 180,
'stream_context' => stream_context_create($opts),
'cache_wsdl' => WSDL_CACHE_NONE,
//'compression' => SOAP_COMPRESSION_ACCEPT | SOAP_COMPRESSION_GZIP | 1
);
