We have a lot of TC56 in the filed and all keep connection to MobiControl server if there is a Wifi or mobile connection.
But on a view devices the agent gets disconnected even if there is an active network connection (other apps can work well over the internet).
After a reset the MobiControl agent remains disconnected.
You can only get the agent connected if you tap on the “Agent Status” in the Device configuration view of the MobiControl agent. But it gets disconnected after a few minutes again.
The connection settings are Perisistent for these devices (like for all other devices)

How can I get these devices pemanently online again?
MobiControl version: 14.4.3
Android Enterprise Agent Versio: several 13.6.0 - 14.0.0
