Hello all, I’m trying to charge my LiFePo4 100Ah 24V battery with the Blue Smart Charger IP65 24V/8A. It has worked before but now it will not charge at all. After plugging in the charger it will keep blinking the test-LED. None of the mode LEDs is on. When I try to connect through the VictronConnect app, it will show up but I cannot connect nor can I change the PIN. When connecting or changing the pin the LEDs on the charger will blink in a certain pattern. The app will display ‘Unable to connect’ Also with no battery connected it will not connect to the app. I did also try long pressing (±3 secs) the mode button; the blue mode lights and orange float, abs, bulk and test will blink quickly alternated of eachother. Does anyone know what the issue might be? Thanks in advance! ---

For future reference: I ended up getting a replacement from Victron because of the faulty unit.
