如何调试没有收到苹果推送通知？

我使用 apn_on_rails 苹果的推送通知我的服务进行整合。

I'm using apn_on_rails to integrate Apple's Push Notifications with my service.

有一段时间，通知似乎没有问题发送。但现在的通知似乎并没有被它使人们的iPhone手机/ ipad公司

For a while, notifications seemed to be sent without issue. But now the notifications don't seem to be making it to people's iPhones/iPads.

根据我们的数据库中，通知被发送（ apn_on_rails 有被更新了 sent_at 字段时，发送通知）。但是，没有人（包括我自己）真正得到通知。

According to our database, the notifications are being sent (apn_on_rails has a sent_at field that gets updated when the notification is sent). But no one (myself included) actually get the notifications.

任何想法，甚至开始寻找调试呢？

Any ideas where to even start looking to debug this?
