[9.060][OPEN] Endpoint Stopped working after EndPoint Server Maint

Hi All
When I first build this UTM end point reported working with one machine.

Then some time after (I would say after the Server Maintenance) this showed "Offline".

I can see one problem in the log files that the UTM "Can't talk to Sophos LiveConnect"
But not why the "Laptop" that has the "endpoint software" installed stopped.
