Just Want to know that does this happen due to any of recent release of ios versions or anything bad happend on server ? Web services code is in Ruby on rails. Please suggest what should I check to fix the problem?

Please help me.

Answer 1

I think it is not a problem related to your Server or recent release of ios versions. It might be the problem with the certificate as mentioned by Eran. The Apple Push Notification Service (APNS) certificate, lasts for one year and must be renewed annually. You can create a new certificate or renew your older certificate.
