MIC of join-request is invalid Chirpstack(V 4.2) move-x cicerone

hello

I cannot perform the join action of the move-x cicerone end node to the network server CHIRPSTACK VERSION 4.2.0

The error is always the same:

MIC of join-request is invalid, make sure keys are correct"
deduplication_id:“3a72e6c5-0d2a-4395-8e6a-c48cb54d525d”

I ASK YOU FOR YOUR HELP
How can I solve this error?

My gateway is active and online in chirpstack.

Thank you for your prompt response

Hey,
I had the same issue yesterday (but my end-device reported it over serial). It worked before and after tinkering with the application key I had this issue. I solved it by deleting my device and re-adding it. Make sure that your application key is the right way around (MSB/LSB) or try adding two devices where you try both ways (one where you paste your AppKey as MSB and one where you paste your AppKey as LSB).
I hope this helps.
Greetings
Mika
