We’ve been seeing this problem on and off for a year.
As the number of our AEP Gateways increases it’s becoming more of an issue.
Given the low number of AEP sales I don’t think it’s a priority for MT to look at without log based evidence.
My hunch is the problem with the LoRa-in node.
Adding a [mqtt in] node to [local host] and sub to topic lora\+\up we can sometimes see uplink messages, but no LoRa-in messages.
A re-deploy of node-red flow often sorts the the problem.
We are testing a dead-mans handle which re-starts node-red via AEP API
POST to http://127.0.0.1/api/command/restart_node_red does it though it will take about 4 mins to re-start.
