可能是由於 APNS 過期或不正確
- 請進入「 蘋果 」> 「 APNS 」> 「 APNS資料 」
- 檢查證書是否過期 - 如發現已過期，請按照說明進行更新
- 如果證書仍有效，請進入「 設備 」>「 設備管理 」
- 按鍵「 設備名稱 」
- 在設備詳細頁面中，向下捲動至 APNS Cert UID
- 如果有 APNS Cert incorrect 的提示，請複制 UID 的最後一部分（一組英文字和數字的組合）
- 轉到 https://identity.apple.com/pushcert/ 尋找與設備 UID 的最後一部分相同的證書。 下載該證書，然後再次到 ESP 更新 APNS
Why my devices are disconnected and unable to manage?
It may due to APNS expiration or incorrect
- Please go to Apple > APNS > APNS Info
- Check if the current certificate is expired. If yes, please follow the instructions to update
- If no, please go to Device > Device Management
- Tap on the Device Name which is disconnected
- In Device Detail page, scroll down to APNS Cert UID
- If there is a notification of APNS is incorrect, please copy the last part of the UID (should be a mix of characters and numerics)
- Go to https://identity.apple.com/pushcert to find the certificate matching the last part of the device UID. Download that certificate and update to ESP again
