It is MDM using APNs.

Hello.

Apple MDM is used.

It is MDM using APNs.

. The topic of mobileconfig is the same as the thing of Subject of APSP-XXX.pem.

. The character string of a device token and PushMagic reached the MDM server after the setup of mobileconfig.

I sent wording of a telegram for device tokens using APNs.

It is replacing by the character string of PushMagic.

Although {"mdm":"xxxxxxxxxxxxx-xxxx-xxxx-xxxx"} is sent via APNs from the MDM server,

iPhone is not reached.

Why is it?

Please let me know the cause considered.
