Why is the SOAP service not responding?

Question

PHP

I'm trying to integrate with the service https://webservice.myschenker.fi/ewebs/dbs_service.svc
They have only 4 methods, I need "getCollectionPointsByPostalCode"
Here is a brief description www.noutopistepaketti.fi/Documents/201604_mySchenk...
For some reason when I send a request, I get the error "Could not connect to host".
Tech support says everything works for them.
Here is my code :

$soapParams = [
            'trace'                       => true,
            'cache_wsdl'             => WSDL_CACHE_NONE,
            "stream_context"      => stream_context_create($stream_context_opts)
        ];

try {
  $client = new SoapClient('https://webservice.myschenker.fi/ewebs/dbs_service.svc?wsdl' ,$soapParams);
  $ty = $client->getCollectionPointsByPostalCode("02750");
  var_dump($ty);
} catch (Exception $e) {
    var_dump($e->getMessage());
}

Thanks

Answer 1

They have 2 versions of the method there,

which in BasicHttpBinding_Idbs_service I didn't reach

which in BasicHttpsBinding_Idbs_service answered

Probably at you the request goes to the first variant. Show this to tech support, I think now they can help with something.
