IOS device gets unenrolled after enrolling

[Dopper57]

Hi, 

Currently were rolling out iPhone 11 to our Airwatch system. Everything goes well at start but after a couple of moments the device gets unenrolled. In the eventlog i get a Break MDM confirmed event. After we reset the phone and try again it works. 

We already disabled compromised protection and there are no compliance policies active except for a SIM-card change. 

Does anybody have a suggestion which we could check? 

Kind regards,

Hi,
Have you verified the device enrollment restrictions?

[Dopper57]

Where should i check those? 

[Noordan]

Devices / Device Settings / Devices & Users / General / Enrollment.

then check the restrictions tab.

The only restriction that i have is a 'global default 20 devices'.

spontaneously I have no other good idea, unfortunately.
