I have a MPPT 75/15 and a mppt 100/30 solar controllers, today was prompted to update victron connect firmware to 2.19 from 2.14. Both Failed at 86%, response timeout. The 100/30 lost its firmware version, the 75/15 retained the 2.14 but will not let me connect until firmware is updated. I tried multiple times on both with the same result each time.
