"PROP_IPv6_ICMP_PING_OFFLOAD" error on Thread DFU

[IvanSanchez]

Running nrfutil dfu thread -pkg /tmp/Thread_DFU-test/app_dfu_package.zip --port /dev/ttyACM0 -f in my Debian box fails consistently with the following error stack:

Address not specified. Using ff03::1 (all Thread nodes)
Using connectivity board at serial port: /dev/ttyACM0
Board already flashed with connectivity firmware.
Opening serial to /dev/ttyACM0 @ 115200

Exception: Failed to set property PROP_IPv6_ICMP_PING_OFFLOAD

On one hand, I'd like the DFU procedure to just succeed. All my attempts to run nrfutil dfu thread -f on Debian fail with this error

On the other hand, as a user, I'd like to see a more meaningful error message - what is PROP_IPv6_ICMP_PING_OFFLOAD and why should I care about it, what should I do to fix that?

Is this error caused by some failure at initializing something more general (e.g. sending the first IP packet)? If there is a root cause for this, I'd like to see it in the error message.

@IvanSanchez
Unfortunately, the issue is not that consistent elsewhere. This typically shows up after flashing the firmware but doing a hard reset after flashing should make it disappear.

Closing as won't fix

Did anyone found any solution to this ?
