Apple stops legacy binary protocol based notifications

APNS has announced that they will no longer support legacy binary protocol from March 31, 2021. Users have been asked to switch to the new HTTP/2 protocol to avoid disruptions to Push notifications capability.

Starting from March 31st, APNS will close legacy binary protocol endpoints with port 2197 and 2195.

Apple Push Notification service server certificate update

APNS made one more announcement regarding the server certificate update.

On March 29, 2021, Apple Push Notification service must incorporate the new root certificate (AAACertificateServices 5/12/2020) which replaces the old GeoTrust Global CA root certificate. To ensure a seamless transition and to avoid push notification delivery failures, verify that both the old and new root certificates for the HTTP/2 interface are included in the Trust Store of each of your notification servers before March 29th.

Note that Apple Push Notification service SSL provider certificates issued to you by Apple need not be to updated at this time.
