Hi
I try the example from here for a DFU OTA: https://infocenter.nordicsemi.com/index.jsp?topic=%2Fcom.nordic.infocenter.meshsdk.v3.1.0%2Fmd_doc_libraries_dfu_dfu_quick_start.html
I'm using 3 nRF52833-DK for this task, but I'm struggling with the last step: "nrfutil dfu serial -pkg dfu_test.zip -p <COM port> -b 115200 -fc --mesh", which throws me this error:

The COM port is correctly chosen and I can also connect via nRF Connect.
Also the bootloader works fine, as checked with the bootloader_verify.py script. What I'm further missing is, how I can set up my mesh network with the 3 nodes, when using the DFU example firmware from the Mesh SDK v4.0 ("nrf5_SDK_for_Mesh_v4.0.0_src\examples\dfu"), since I cannot see any unprovisioned proxy nodes in the Mesh app.
Any ideas what can be wrong here?
Edit:
After using nrfutil dfu serial -pkg app_dfu_package.zip -p COM61 -b 115200 -fc 1, i got this error:
