Hi Kudos,

daily will happen more than 5 times.

Hi,

These primary uplink logs indicate that the connection is failing over to the cellular. If you looked at the uplink statistics of your Appliance, you will see historical information regarding ping to 8.8.8.8 (by default) and its latency. If you are seeing packet loss and it is consistent with those event logs, then please check with your ISP as you may have an issue with your Internet connection.

You can also add the gateway IP on Uplink statistics so that it would tell you whether you are losing LAN connectivity or only to 8.8.8.8 when you are seeing these events.

hope this helps.

It can also happen if the link is overloaded and dropping packets.
