Uploading the APNs(Apple Push Notification service) certificate (.p12) is failed.

In networks (inspection of the Chrome), I got a message as following:

1. error: "UpstreamError"
2. message: "500 Internal Server Error: {\"error\"=>{\"title\"=>\"We're sorry but something went wrong\", \"message\"=>\"We have been notified of this error and will be investigating it. If you see this error frequently, check the Zendesk status page at https://status.zendesk.com\"}}"
