APNS: The certificate is revoked

Question

My iPad app uses an ASP.Net server to send APNS messages (using MoonAPNS) to the app when a new document is uploaded to the server.

I used MMC to import new certificates last week (Thursday) and had it working with an ad-hoc distribution version of the app.

Today, I tried to upload a new document to the server and received the error:

Server Error in '/' Application.

The certificate is revoked

The things is, between last Thursday and today I haven't revoked any certificates / provisioning profiles / etc.

Anyone have an idea of why this might have happened?

Answer 1

I eventually gave up trying to figure this one out and brute-force fixed it by removing then renewing all of the server certificates.

Still no idea what caused the initial problem but this at least is a work-around.
