I am having a serious brainfart and my google searches aren't giving me what I need. My MacMini server running Sierra that I'm using for Netboot and Caching (and hopefully soon Profile Manager) is telling me that the Apple Push Notification Service certificates are expiring soon (March 14) and it lists
apns:com.apple.alerts
apns:com.apple.calendar
apns:com.apple.contact
apns:com.apple.mail
apns:com.apple.mgmt
although I'm not using calendar, contacts, and mail at this time. The notification tells me the cert can be renewed in Server. I go to Server > Certificates and the only cert it shows is "Server Fallback SSL Certificate" that I don't remember ever setting up. I logged into the Apple Push Certifications Portal and I see my server listed but only a Revoke button next to it. How on earth do I renew the cert or even just start over with a brand new one? I can't find anywhere on the server nor in the Portal an option to create a new APN cert. I know I've done this before in the past but this is really confounding me for some reason.
