I'm seeing the following error message when attempting to perform a simple payment using the PayPal Adaptive Payments API and the Explicit Approval Payment Flow in the sandbox environment:
Proxy Error The proxy server could not handle the request GET /webapps/adaptivepayment/flow/expresscheckoutincontextremembermeflow. Reason: Error during SSL Handshake with remote server
As per this related post, this issue has supposedly been resolved, but I'm still unable to perform a simple payment in the sandbox environment.
The API call to generate a payKey is returning successfully:
{
'responseEnvelope': {
'ack': 'Success',
'timestamp': '2013-04-01T10:00:33.572-07:00',
'build': '5563463',
'correlationId': '9ddb6d34b8b31'
},
'paymentExecStatus': 'CREATED',
'payKey': 'AP-30241506EH984280M'
}
and the following series of redirects are occurring:
https:// www.sandbox.paypal.com/webapps/adaptivepayment/flow/pay?expType=light&paykey=AP-30241506EH984280M
redirects to: https:// www.sandbox.paypal.com/webapps/adaptivepayment/flow/payinit?iframecookie=1364835660832&paykey=AP-30241506EH984280M&expType=light
which redirects to: https:// www.sandbox.paypal.com/webapps/adaptivepayment/flow/corepay
which redirects to: https:// www.sandbox.paypal.com/webapps/adaptivepayment/flow/expresscheckoutincontextremembermeflow
which gives the 500 proxy error after approximately 210 seconds.
Additionally, if I attempt the workaround of logging into developer.paypal.com in another tab first, I get a 404 error on the initial request: https:// www.sandbox.paypal.com/webapps/adaptivepayment/flow/pay?expType=light&paykey=AP-45P14958V28124917
I've searched and searched and poked and prodded this issue to death...anyone else seeing this problem, and does anyone have a working resolution?
