What would cause all systems to switch to unmanaged at check-in? APNS Certificate has been renewed, all other certificates look good from what I can tell and nothing else has changed. I desperately need help as right now my JSS is off until I can resolve this to prevent further damage. Any help is appreciated
Is something deleting the management account on your Macs? Or are you using an account for management that doesn't exist on them? I assume its not the latter since you mentioned they're checking in at least once. I also don't know for sure if on check in, if the local account for management is getting removed that it would cause them to go into an "un-managed" state, but perhaps.
Do you have physical access to any of these Macs? or SSH? If so, get in and check the jamf.log to see what the last check-in ran as far as policies. It might point you in the right direction.
So yesterday afternoon around 4pm I just started receiving emails that users were being removed from the managed group. 22 emails later I unplugged the JSS. Nothing has changed in our setup. Thats why I'm thinking something expired but don't see anything.... I have access to some of these systems so I will check the logs
I also checked the jamf.log file and nothing happened from the client side. Just business as usual.
Log for 16:43 yesterday for one of the systems that became unmanaged.
Tue Jul 15 16:43:18 MacBook Pro - jamf: Checking for policies triggered by "recurring check-in"...
Received notification at 16:43 that a system was removed from All Managed Clients
