Hi
Currently facing join accept issue from server side. Chirpstack is not triggerring the join accept on random basis while the devices are correctly registered and have valid device nonce and keys.
Event tab is not showing any error. I have restarted the chirpstack but not working.
Chirpstack Version 4.17.0
Regards
Piyush
Adding here the trace logs,

Above logs seems to be fine but on UI there is no join accept message.
