Having difficulty setting this up. I keep getting an error on the app that says " Server does not support iPhone notifications. (Error code 503).
I've allowed feedback.push.apple.com:2196 and gateway.push.apple.com:2195. I checked the certificate at /bin/webapps/helpdesk/WEB-INF/Helpdesk.woa/Contents/Resources/PushNotificationDevelopmentCertificate.p12.
This is a new install that isn't in production yet. I just installed 12.1. Is there something I missed during the install?
