Cannot connect to APNS

Q: I experience iOS certificate problems. What does “Cannot connect to APNS” error mean?

A: This error means that the APS certificate you have uploaded is not valid and Apple rejects the connection to their servers. The possible reasons are:

  • You are using wrong gateway. For example you are trying to connect to Production gateway with the certificates from Sandbox.
  • The private key is incorrect or does not match the certificate. Please make sure you export the private key from your Push Notification certificate, not your Developer certificate.
  • The certificate is not valid or expired. Just get the new one from the iOS developers portal!
