Hey all!
I have around 200 iOS devices enrolled in Hexnode and they were working fine till a few days back when a few of my devices (around 20) stopped responding. All of them are switched on and also has an active internet connection. But some of them are shown as inactive as well. Here are some of the things that I tried out to fix the issue:
Restart the device
Connect the device to another network
Check the validity of the APNs certificate [still valid – around 125 days left]
There devices are still unresponsive even after performing the above troubleshooting methods. Does someone have any idea on how to fix the issue?
