AWS SNS - Platform application is disabled

Question

We use Amazon SNS to send push notifications to our users. We recently renewed the certificates but for some reason we nog get the following error:

<?xml version="1.0" encoding="UTF-8"?>
<ErrorResponse xmlns="http://sns.amazonaws.com/doc/2010-03-31/">
   <Error>
      <Type>Sender</Type>
      <Code>PlatformApplicationDisabled</Code>
      <Message>Platform application is disabled</Message>
   </Error>
</ErrorResponse>

We haven't changed anything to the code or to the certificates. When I verify the certificates using openssl s_client -connect gateway.sandbox.push.apple.com:2195 -cert myapnsappcert.pem -key myapnsappprivatekey.pem everything also works fine. The only problem is that the notifications for iOS won't be sent due to the error. Android is working fine.

Answer 1

The error can caused because your p.12 is expired, you can create a new one or update the current in AWS SNS.
