what might be the reason for no data transfer from device any clue?

We have the same issue. One of our clients has reported that our chirpstack platform isn’t receiving almost all of their LoRa device uplinks anymore, only uplinks from one device are being received. However, devices in other applications work fine. This started on 5th december, about 1 month after upgrading from an older v3 version to the then latest chirpstack-application-server v3.17.8 and chirpstack-network-server v3.16.5. We are currently unable to upgrade v4 since we are using json as marshaler and our lora gateways have the chirpstack-gateway-bridge version 3.13.3.

Also another issue that might me related, any lora devices that are inactive for a while recently went from the corret Last seen at value, e.g. 3 months ago to n/a. This is the case for all inactive devices.

Maybe your node did not receive the Join accept and is trying to rejoin forever?

No, the join request is accepted, and the node sent one uplink and then stops. However, I think I have found the problem. I’m not sure exactly how, but it appears that the devices were moved to a different application or the application ID changed somehow, and therefore the LoRa nodes are no longer recognized by Chirpstack.
