Zend_Rest_Client Error on localhost

I'm using Zend_Rest_Client to connect Zend_Rest_Server, everything seems to be fine, but when I try to get () from the server, I get this error:

Zend_Http_Client_Adapter_Exception: Failed to connect to TCP: // local: 80. Error # 10060: A connection attempt failed because the related party did not respond properly after a period of time, or the established connection failed because the connected host was unable to respond. in C: \ WWW \ zf_1_72 \ libraries \ Zend \ Http \ Client \ adapter \ Socket.php on line 148

here is the code i am using

$client = new Zend_Rest_Client('http://localhost/my_application/api/index/');       
$client->auth($key);
$result = $client->get();

      

        
        
        
      

    

thank for any advice
