CSCwb93826	Push notifications not working on Webex 42.5.1

Problem Description

The Network Push Server (NPS) application is no longer able to connect to the Apple Push Notification Server using tokens since ADP 2022.04 introduced certificate authentication.

Background

The NPS application is no longer able to connect to the Apple Push Notification Server using tokens since ADP 2022.04 introduced certificate authentication. Prior to ADP 2022.04, the NPS application, when using tokens to validate with APNS, did not send a certificate. With ADP 2022.04, it now sends the certificate of the server (which is incorrect). The connection to APNS then fails.

Problem Symptom

The Push Notification service does not work.

Snippet from the NPS logs:

Workaround/Solution

Workaround

Do not upgrade to ADP_Rel_2022.04_1.340, or roll back to the previous release if this functionality is needed.

Solution

The fix in ADP_Rel_2022.05 is available to download from NotificationPushServer_2022.05_1.302.
