We started seeing this behavior with a subset of the devices on our platform (we have many other devices joining successfully and showing join accepts in the GUI). The application server shows join requests, but no join accepts. However, I have an application that consumes from the
gateway/+/command/down mqtt topic, which if I understand correctly is the topic used to send packets down to the end devices and I DO see the join accept packets there.
Any suggestions on where to look for the problem? I have tried several things (noted below) and cannot pinpoint the issue.
- Rebooting the gateways
- Restarting the Chirpstack Gateway Bridge
- Restarting the Chirpstack Application and Network servers
- Pointing the gateways at an older Lora Gateway Bridge (pre-Chirpstack namechange)
