PayPal EC Problem: Received HTTP code 405 from proxy after CONNECT

I have a PayPal business account. In my site, PayPal IPN is ok. But, PayPal Checkout Express is have a problem. This is that warning:

An error occurred when we tried to contact the payment processor. Please try again, select an alternate payment method, or contact the store owner for assistance. () - (56) Received HTTP code 405 from proxy after CONNECT


I don't know about that.

Additional information: domain: www.pettags4less.com, Hosting at www.id########################, Use ZenCart v. 1.3.8a, link cURL test http://pettags4less.com/curltest.php and link ipncheck http://pettags4less.com/ipncheck.php .

I am very newbie. Please tell me more detail, how can I do to solving that problem.
