PHP: SoapClient Error When I Using Custom Port

When I use port with URL I get error:

Code:

    try {
        $options = [
            'login' => "999999",
            'password' => "999999testtest"
        ];
        $request = new SoapClient("https://erpefaturatest.cs.com.tr:8043/efatura/ws/connectorService?wsdl", $options);
        print_r($request);
    } catch (Exception $exc) {
        print_r($exc);
    }

Error: SOAP-ERROR: Parsing WSDL: Couldn't load from

But wihthout port I don't get error:

Code:

    try {
        $options = [
            'login' => "999999",
            'password' => "999999testtest"
        ];
        $request = new SoapClient("https://connectortest.efinans.com.tr/connector/ws/connectorService?wsdl", $options);
        print_r($request);
    } catch (Exception $exc) {
        print_r($exc);
    }

I don't understand the problem. Any idea?
