Magento PayPal Post Back Bug

Maybe anyone can help solve this issue. Everything worked fine ages, and yesterday, PayPal post back failed. It stopped updating any statuses.

Log is showing

    [exception] => PayPal IPN postback failure. See paypal_unknown_ipn.log for details.
    [__pid] => 26563
 

 had the same situation and the link that Sergey posted did help me. Let me share my solution.

The fix should be applied to the app/code/core/Mage/Paypal/Model/Ipn.php file (copy it to local of course).

Find the protected function _postBack(Zend_Http_Client_Adapter_Interface $httpAdapter) and change the line

 

Line:
144

===============
OLD Code
===============

        $httpAdapter->setConfig(array('verifypeer' => $this->_config->verifyPeer));
        $httpAdapter->write(
            Zend_Http_Client::POST,
            $postbackUrl,
            '1.1',
            array('Connection: close'),
            $postbackQuery
        );

===============
NEW CODE
===============
        $httpAdapter->setConfig(array('verifypeer' => $this->_config->verifyPeer));
        $httpAdapter->write(
            Zend_Http_Client::POST,
            $postbackUrl,
            '1.1',
            array('Connection: close', 'User-Agent: Mozilla/5.0 (Windows NT 6.1; WOW64; rv:38.0) Gecko/20100101 Firefox/38.0'),
            $postbackQuery
        );
