Zend SoapClient Thowing exception "Could not connect to host"

I am using ZEND framework, My requirement is below:

Client provided an XML file that i imported manually in my SoapUI and added certificate under "File->Preferences->SSL Settings->Key Store" and also supplied "Key Store Password" and set "Require Client authentication" true.

Then i changed request url with another one, after completing all above steps I can successfully get the response.

1- Import XML by adding new soap project

2- Add certificate under "File->Preferences->SSL Settings->Key Store" and also supplied "Key Store Password" and set "Require Client authentication" true/checked.

3- In XML file we have location: soap:address location= http://ift.tt/17gCOov

But after completing step 1 and 2, we changed the request url to http://ift.tt/17gCOox manually and it is working expected.

I did same thing in php/zend code

        ini_set('soap.wsdl_cache_enabled',0);
        ini_set('soap.wsdl_cache_ttl',0);
        $certlocation = APPLICATION_ROOT . '/public/scripts/somename.pfx';
        //$certlocation = APPLICATION_ROOT . '/public/scripts/example.ex.com.p7b';
        //Used both above certs


        $wsdlLocation = APPLICATION_ROOT . '/public/scripts/CommonIO.wsdl';

        $options = array(
            "trace"         => 1, 
            "exceptions"    => true, 
            "local_cert"    => $certlocation, 
            /*"passphrase"  => "somepassword",*/
            "uri"           => "urn:xmethods-delayed-quotes",
            "style"         => SOAP_RPC,
            "use"           => SOAP_ENCODED,
            "soap_version"  => SOAP_1_1,
            "location"      => "http://ift.tt/17gCOox"
        );

        $client = new SoapClient($wsdlLocation, $options);
        Log_Manager::info('Soap Client Object Created successfully...'.$client);

        //$client = new Zend_Soap_Client('http://ift.tt/17gCOoB', $options);


        $response = $client->SomeMethod($request_obj);

In log I found "Soap Client Object Created successfully" printed even not sure Is it correct or not but I am able to create an object of SoapClient But just after that it thows an below exception (faultcode: HTTP, faultstring: Could not connect to host).

ReceiverSOAP Fault: (faultcode: HTTP, faultstring: Could not connect to host)

Any help is truly appreciated.
