We use three APX120 with a Sophos XG115 (SFOS 19.5.3 MR-3-Build652).
All was running fine for more than two years.
Since two weeks, all the accesspoints are "inactive". We have tried to disconnect them, rebooted them several times but the do not go online.
We can ping all of them.
What can we do to fix that problem?
