I have Chirpstack V4 that ran well with the Dragino gateway DLOS08 for a year. However, after running “apt-get upgrade” to upgrade the nodeRed and nodeSJ, the chirpstack doesn’t work anymore. Chirpstack showed this error "ERROR chirpstack::gateway::backend::mqtt: MQTT error error=I/O: connection closed by peer
I decided to remove/purge the following: mosquitto \ mosquitto-clients \redis-server \redis-tools \PostgreSQL\chirpstack-gateway-bridge & Chirpstack
Then I reinstalled the Chipstack again (like from the crash).
After reinstalling, like before, I can see gateway data (using mosquitto-sub or check status with systemctl):
Apr 30 14:31:57 raspberrypi chirpstack-gateway-bridge[30698]: time=“2024-04-30T14:31:57.781092822-03:00” level=info msg=“integration/mqtt: publishing event” event=up qos=0 topic=us915_0/gateway/a84041ffff21c16c/event/up uplink_id=41318
But the chirpstack errors is still there:
Apr 30 14:23:15 raspberrypi chirpstack[2360]: 2024-04-30T17:23:15.676202Z ERROR chirpstack::gateway::backend::mqtt: MQTT error error=I/O: connection closed by peer
Apr 30 14:23:15 raspberrypi chirpstack[2360]: 2024-04-30T17:23:15.707854Z ERROR chirpstack::gateway::backend::mqtt: MQTT error error=I/O: connection closed by peer
Please help me with this issue.
Worse case, if I need to reinstall from the crash, what else I should remove.
(Note: This is a remote computer; I cannot reinstall the RasberryPiOS. It will lose the remote connection).
Thanks for your support.
