How do I renew the SSL certificate for my ios push notification provider?

Question

A bit under a year ago, a teammember who has now left built an iphone app which is on the app store, and an ios push notification daemon which sends it notifications. Today, the daemon started spitting out SSL certificate errors - it seems the daemon's certificate has expired.

I've got the username and password of the developer account, and I've logged into the provisioning portal to create a new certificate. If I go to manage the App ID of our older apps that we no longer support, I see this:

But if I manage the App ID of the one I'm trying to renew, I see this:

Why isn't there an option for me to generate a new push SSL certificate for this app? How do I renew the push daemon's ssl certificate without it?

Will we need to rebuild and resubmit the app?

Answer 1

If the certificate has expired, you must generate and download the new certificate, remove older certificates, and install the new on the server.

Resubmit the app is not necessary, just install the certificate on the server, no changes happens on client apps.
