UDMI discovery message - fails to reconnect after token expiry

[noursaidi]

While running the ATA, after about 25 minutes, the UDMI discovery publisher stops publishing. Looks like a JWT refresh issue.

The cloud logs show a disconnect due to token expiry:

jsonPayload: {
disconnectType: "SERVER"
eventType: "DISCONNECT"
protocol: "MQTT"
resourceName: "projects/daq1-273309/locations/us-central1/registries/UDMS-AUDITOR/devices/2746576174755753"
serviceName: "cloudiot.googleapis.com"
status: {
code: 16
description: "UNAUTHENTICATED"
message: "SERVER: The authorization token expired."
}
}

The daqrun logs show the device trying to reconnect unsuccessfully

on_connect Connection Refused: bad user name or password.
on_disconnect 5: The connection was refused.
Waiting for 1.908 before reconnecting.
