Root-cause analysis

Diagnosed cause

Upstream uplink/WAN link down or device hardware unresponsive

RCA confidence84%

Above the 70% threshold — a fix can be pre-formed.

Reasoning

The device has been unreachable from the cloud for over ten minutes with no telemetry, consistent with a downed uplink or a hung device rather than a transient blip.

Generated by heuristic

Evidence trail

device_unreachableDevice unreachable: yes

Device is not responding to the Meraki cloud at all.

uplink_downUplink down for: 11min

Uplink has been down long enough to rule out a transient flap.

packet_lossWAN packet loss: 100%

Elevated packet loss preceded the outage, pointing upstream.

Normalized telemetry (3)

WAN packet loss100%

Proposed fix

Restart device and confirm WAN failover

Restart the unreachable UniFi device through the controller, then confirm the gateway failed over to the secondary WAN before closing the fault.
