I have a problem similar to this: Apple Push Notification in Production Environment : Unable to get local issuer certificate but in my local computer. I followed this tutorial: http://www.raywenderlich.com/3443/apple-push-notification-services-tutorial-part-12 but in this step
openssl s_client -connect gateway.sandbox.push.apple.com:2195 -cert PushChatCert.pem -key PushChatKey.pem
It says:
(A lot of number and letters) Verify return code: 20 (unable to get local issuer certificate)
What the problem is? Thank you
