Reply to Apple Push Notification service server certificate update
We have the new cert installed on our server however when we try to connect using: ~$ openssl s_client -showcerts -connect api.sandbox.push.apple.com:443 We get the following CONNECTED(00000003) depth=1 CN = Apple Public Server RSA CA 12 - G1, O = Apple Inc., ST = California, C = US verify error:num=20:unable to get local issuer certificate verify return:0 Certificate chain 0 s:/CN=api.development.push.apple.com/OU=management:idms.group.533599/O=Apple Inc./ST=California/C=US i:/CN=Apple Public Server RSA CA 12 - G1/O=Apple Inc./ST=California/C=US----BEGIN CERTIFICATE ......... This line: unable to get local issuer certificate is what concerns me.. What are we doing wrong here?
