Hello! Chirpstack version: 4.17.0, concentratord 4.7.0, mqtt-forwarder: 4.5.1, gateway-mesh: 4.1.3.
Problem: I'm trying to set Chirpstack Gateway Mesh Configuration, I have border Gateway. In chirpstack-gateway-mesh.toml I've set "border_gateway = true".
In chirpstack-mqtt-forwarder.toml I've set:
[backend]
enabled="concentratord"
[backend.concentratord]
event_url="ipc:///tmp/gateway_relay_event"
command_url="ipc:///tmp/gateway_relay_command"
Is it right configuration for border gateway?
When I've just set all parameters all worked. But after gateway reboot end-devices can't set snything to gateway. When I've tried to rejoin them I got no JoinAccept:

Any ideas why this happening? I've tried to delete sockets after reboot, but it didn't help. Only manual service restart works :(
