MK-3 USB / VEFlash Error at step 'Connect part 2'

Hello,

I have multiplus 40/3000 and my old FW is:

2620158 i believe i need 2620159 with im trying to update.

But having error.

I dont have problem to VeConfig, Victron Connect does not work becouse my FW is to old.

Swapped device, changed ports and all... still no luck.


Tried to google solution but cant find any,


I want to update FW and go with Generator configuration as every 60 sec there is a swap between charger to inverter.

I've tried another ethernet port and no luck still.

I'm under off grid so I only has batteries connected.
