Bias-Free Language

The documentation set for this product strives to use bias-free language. For the purposes of this documentation set, bias-free is defined as language that does not imply discrimination based on age, disability, gender, racial identity, ethnic identity, sexual orientation, socioeconomic status, and intersectionality. Exceptions may be present in the documentation due to language that is hardcoded in the user interfaces of the product software, language used based on RFP documentation, or language that is used by a referenced third-party product.

Defect Information

Defect ID Headline
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:

2022.05.12 18:41:51:315 EDT | Warn       | HTTP | nps_server_0 | 196

    Executing the request failed: Received fatal alert: unknown_ca

2022.05.12 18:41:51:315 EDT | Warn       | APNS | nps_server_0 | 197

    APNSHttpCommunicator.sendMessage() IOException occurred in sending the HTTP request to APNS : javax.net.ssl.SSLHandshakeException: Received fatal alert: unknown_ca

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.
