I have many devices running the same program using node-RED’s MQTT node to publish messages to Losant’s MQTT Broker and to subscribe to the same broker for device commands.
The devices have correct authentication as they connect initially without issue but then they timeout (according to Losant) some of the devices are able to successfully reconnect and others aren’t.
For example device 4697:
Connects to Losant without issue:
But since December 3rd it has disconnected many times and continues to do so often citing the keepalive timeout:
Another device 4683 running the same program (with the only difference being authentication) connected successfully initially:
But unlike the other device it does not reconnect regularly and instead gets stuck in the connection process:
It seems that these disconnects are common across all connected gateways that are connected to Losant here is another example device 4723:
It is very strange as this issue started in the past few months as when we were testing this project initially within Losant we did not see these types of disconnects with our gateway devices.
Have there been any changes to Losant’s broker that need to be accounted for?
Any ideas on where or why this might be happening?
