Error during DFU nrf52 with nRF Connect 3.3.1

[Andrew_Engineer]

Hello,

target hardware: nRF52832

Software SDK15.3  Softdevice 6.0

Application nRF52 development board + nRF Connect 3.3.1

Target board loaded with softdevice and bootloader and getting detected by nRF Connect as DFUtarg.

we also generated zip file what suppose to be loaded in target board.

This combination works for us for last few years ie performing DFU using nRFConnect.

Recently when we started DU we got follow message:

We did try to use different computer, different nRF52 development board, but results always the same.

Any word of advise, what it can be and how to solve it greatly appreciate it.

Thank you,

Andrew
