Mosyle & ASM - Enrolling with management server failed

[TheFopp]

I've been setting up Apple School Manager and Mosyle to manage some new Macs we are getting to replace our old Mac DAW suite. Previously we used Mac Server with VPP.

I've now got ASM up and running, and the old VPP licences moved over to Apps & Books in ASM.

 

I've connected ASM to Mosyle, and set up a basic Automatic Enrolment Profile to test the system.

When I boot up the new Macs, the DEP takes over and Mosyle/ASM starts to go through some of the setup screens, but when it gets to the Remote Management screen where it tries to retrieve enrolment profile, it shows the error:

 

'Enrolling with management server failed.

The server certificate chain for your organisation's MDM server was not properly set up.'

 

As far as I can tell it is all setup correctly. Has anyone else had this issue and if so did you figure out what was wrong?

This can be a DEP issue where your MDM is not open for Port 8443?

 

I assume you have a current APNS Cert?
