Hi, I have 2 x Victrom MPPTs, battery monitor, colour controller and 3kw charger inverter. I've had no problems using victronconnect to connect to either old the MPPTs until today even one of them (100/50) has stopped connecting at 20% every time. The other one (150/75) continues to work fine. I've tried 2 different android devices that both worked fine in the past and now the same issue on both. I've followed the trouble shooting steps to reset the Pin using the PUK and I get error:ff00
Both mppt are on firmware 1.46.
I've just seen there us an update to the victron connect app so applied this and still no luck
