Join request loop error:validate dev nonce error

I have a RAK7243 gateway, I want to use the non-standard channel of the CN470 band, and I have configured these channels in the global_conf.json file, but on the built-in chirpstack server of the gateway, I see the join request loop in both gateway and node interface, as shown in the figure, the error is “validate dev nonce error”
The access method is OTAA, class A, and I’m sure the APP KEY and network key are right.


Did you find any solution? I have also same problem.

Hello @it_baadai @elims,

What end-node are you using?
Could you share the global_conf.json?
Have you tried re-registering the device with the same and/or different AppKey/AppEUI?

@it_baadai please share more information about the case:
Are you using the same gateway?
Is the error exactly the same?
Is it a single case with a certain node or do you have this issue with different nodes?

Best Regards
