The Cisco meraki Cloud is having difficulty communicating with this device, and how to resolve this alert.

Overview

Similar to Has never connected to the Cisco Meraki Cloud, this alert indicates there is potentially a firewall blocking key traffic to let devices check-in reliably.

Connecting to the Meraki Cloud is what allows the hardware to show as online in the Meraki Go app. For hardware to successfully check-in with the Meraki Cloud controller, the following requirements must be met:

  • The hardware must have a valid IP assigned. If DHCP does not automatically provide your hardware with an IP address, reference the static IP assignment article for help assigning an IP address to your device.
  • UDP port 7351 must be allowed on any firewalls or devices upstream. The Meraki Go hardware uses the UDP protocol on the referenced ports to check-in to the cloud.
