cnMeastro / cnPilot Alarm

I have a strange alarm in cnMaestro that I have not been able to resolve. This is on 14 of 30 AP’s.

“Tunnel on interface [bcp0] went down”

Cloud cnMaestro 2.4.2
cnPilot e510, v 4.1-r3

No tunnels configured. Very strange forward AP, 1 SSID with Pre-shared key, VLANS

Any ideas?
