How to stop AP One AX pinging google DNS every minute?

Hi

I’m trying to understand and eliminate why my new AP One AX is pinging google before implementing these devices to move to wifi 6.

The network topologoy uses a Pepwave HD2 to connect to the internet, then network switches, APs, devices etc via a SonicWall in Layer 2 Bridge Mode to perform threat detection and management. The SonicWall is detecting and managing the pings to google.

The network uses cloudflare for DNS. I’ve disabled InControl2 and WAN health monitoring from the AP One in case one of those is the root cause.

Any ideas please.

Thanks
David
