We are aware that PayPal rolling out upgrades to make use of SSL/TLS SHA256 for security purposes. Today i met with strange issue on PayPal Sandbox mode for my PayPal Adaptive Application even though my site follows HTTPS. To add further, same application works fine in Production(not sandbox).Please enlighten me, was this an issue in Application or Rollout issues? same issue reported in PayPal community but no response https://www.paypal-community.com/t5/About-Payments/Adaptive-payment-api-is-sending-Proxy-error/m-p/1091510

The proxy server could not handle the request AdaptivePayments/Pay
Reason: Error during SSL Handshake with remote server

    Same here. Integration tests started to fail without any code-change, so I assume it is something on PayPal side. – Mano Kovacs Jul 27 '16 at 20:52
  • Just added an edit to my comment below - hopefully that resolves the problem. – Jonathan LeBlanc Jul 28 '16 at 13:51

    Yes It has fixed now.I was able to complete my test in my PayPal Sandbox.So it implies that my application passed the new changes in Test sandbox and it will be OK when this code rolled out in production as expected? – Jahir Jul 28 '16 at 15:57

Edit July 28th, 9:50am EDT: It appears the teams were able to track down what they believe to be the issue overnight, and released a code fix. Can you please verify that the problem has been fixed? I'll report back if that's not the case. Thanks.

We've had a few reports about failed requests on sandbox. I'm working with the sandbox and support teams internally in PayPal to figure out what's going on. Right now it looks like they're seeing the error responses and have teams on it to diagnose the problem. Just to note, this does look like it's restricted to sandbox and not any of the production servers. I'll post back when I hear more.

    +1 we are also experiencing this error with no code changes in our sandbox environment for PayPal adaptive payments. – HonourCode Jul 27 '16 at 23:05

    Correct @Jahir, if the code is working on sandbox and your application keys have been approved, it should work seamlessly when you push live. Just make sure to switch from sandbox mode with your sandbox keys to live mode with your live keys. This issue was only related to sandbox, so you should not run into any issues in production. – Jonathan LeBlanc Jul 28 '16 at 16:50
  • @JonathanLeBlanc this problem has resurface the for the last few days now. Any status? – Stephen McDowell Aug 18 '16 at 02:29
