I checked your account, and I do show that requests are reaching PayPal and PayPal is sending back an API response for every request. Most were successful, some returned an API error but none the less everyone did generate a successful response back to your system. Make sure that the code that you are using is correct, and that it is set up to read the response that is being sent back. You can find some sample code that may help you here.
