Hi,

Greetings!

I am using below setup

nRF52832

Mesh SDK 4.0.0

SDK 16.0.0

Application Example: light_switch_client_nrf52832_xxAA_s132_7.0.1

Issue:

Using above setup, I use sensor server model publish the Sensing sampling data，The Sensor device work fine about a month.

From yesterday,the Sensor device do not publish sensor data.I try debug and find the NRF_ERROR_FORBIDDEN error from:

[net_state.c] net_state_iv_index_and_seqnum_alloc

the logs:

I try reboot the device and can not restore.

Our other sensor device work longer than that device and still work fine.

How to resolve this issue?

Thanks in advance.
