About push notifications on iOS

Question

I tried sending Apple's test message, but the following error occurred and I was unable to send the message.

テスト メッセージを送信できませんでした。エラー: {"error":{"code":"BadRequest","message":"The Apns certificate is expired.. TrackingId:b626a55a-f74f-4b6a-890d-14ec21f0002f,TimeStamp:12/10/2023 11:50:23 PM +00:00"}}。 テスト メッセージを送信できませんでした。エラー: {"error":{"code":"BadRequest","message":"The Apns certificate is expired..

I was able to successfully send a test on Android.

Is there a reason?

Thanks for posting your question in the Microsoft Q&A forum.
The error message indicates that the APNs (Apple Push Notification service) certificate used for sending push notifications to iOS devices has expired. This certificate is crucial for establishing a secure connection between your server and Apple's push notification service.

To resolve this issue, you need to renew and update your APNs certificate.
