I have referred the provided link Establishing a connection to Apple Push Notification service (APNs). And wanted to highlight that although our APNs certificate is valid until 09 August 2025, we have been unable to send notifications since 22nd April 2025. The error we are encountering is: "java.io.IOException: keystore password was incorrect". After encountering the above APNs exception, we created a new APNs certificate, but unfortunately, we are still facing the same issue. We are receiving the following notification response, but the users are not receiving notifications on the iOS mobile application. Message(Id=1; Token=9C105A434496F9C8E6A47819DAA4C402CF0C231F8219F22AD4FFBD5D0300D832; Payload={"aps":{"alert":{"title":"Message from : ta785","body":"Sender Contact Number : 2341561726\nMessage : test"},"sound":"default"}}) We suspect this issue may be related to recent changes in the APNs certificate authority, specifically the transition to the USERTrust RSA Certification Authority. Given that we are still using a valid APNs certificate, we are unsure whether this transition has impacted our configuration or caused the issue. Could you please guide us or provide support to troubleshoot this error? Any assistance in resolving this issue will be greatly appreciated.
