Anyone else seen where all devices going through an MPLS via Firewall have stopped showing as being Contacted and stop updating their configuration.
All Firewall rules as per dashboard are correct
Just the access points? Setup a port on the switch the same as the AP and try attaching a computer to test/verify to ensure there isn't connectivity issues. If you cycle one of the APs does it come back online?
From the dashboard go to Help>Firewall Info
You'll need to verify those things aren't being blocked somewhere between your devices and the internet. Likely your edge firewall or MPLS network.
