Paypal Adaptive Payments PPConnectionException in PPHttpConnection.php - php

Question

I currently try to implement chained payments using the adaptive payments sdk. I receive this error
PPConnectionException in PPHttpConnection.php line 91:
error:14094410:SSL routines:SSL3_READ_BYTES:sslv3 alert handshake failure
My example code looks like this
$payRequest = new \PayPal\Types\AP\PayRequest();
$receiver = array();
$receiver[0] = new \PayPal\Types\AP\Receiver();
$receiver[0]->amount = '7.50';
$receiver[0]->email = "admin#example.de";
$receiver[1] = new \PayPal\Types\AP\Receiver();
$receiver[1]->amount = '2.50';
$receiver[1]->email = "seller#example.de";
$receiver[1]->primary = "true";
$receiverList = new \PayPal\Types\AP\ReceiverList($receiver);
$payRequest->receiverList = $receiverList;
$requestEnvelope = new \PayPal\Types\Common\RequestEnvelope("de_DE");
$payRequest->requestEnvelope = $requestEnvelope;
$payRequest->actionType = "PAY";
$payRequest->cancelUrl = "http://example.de:8080/payment/cancel";
$payRequest->returnUrl = "http://example.de:8080?returned";
$payRequest->currencyCode = "EUR";
$payRequest->ipnNotificationUrl = "http://example.de:8080";
$sdkConfig = array(
'mode' => 'sandbox',
"acct1.UserName" => "jb-us-seller_api1.paypal.com",
"acct1.Password" => "WX4WTU3S8MY44S7F",
"acct1.Signature" => "AFcWxV21C7fd0v3bYYYRCpSSRl31A7yDhhsPUU2XhtMoZXsWHFxu-RWy",
"acct1.AppId" => "APP-80W284485P519543T"
);
$adaptivePaymentsService = new \PayPal\Service\AdaptivePaymentsService($sdkConfig);
$payResponse = $adaptivePaymentsService->Pay($payRequest);
if ($payResponse->responseEnvelope->ack == "Success")
{
redirect('Location: ' . 'https://sandbox.paypal.com/webscr?cmd=_ap-payment&paykey=' . $payResponse->payKey);
}
else{
die('error');
}
The solutions I found do not seem to work ... any ideas? Currently testing from localhost.

Answer 1

I'm not aware of the actual solution or cause of the error.
What fixed it for me was testing it on an actual server instead of my localhost enviroment.
I also updated the packages to the latest version since there were many changes regarding tls. Older examples do not reference working libaries.
