XKTTSUEERCRR 5050 SMD WS2811 16.4ft/5Metre 60 LEDs/m 300LEDs RGB Flexible Waterproof Strip Lighting Addressable Dream Color LED Kit + Remote Controller+ Power Supply Adapter

When I hooked up to my power supply the lights would just flicker blue. The control box did not do anything just showed numbers but didn't change the lights. I tried buying a second control box and a new power supply and still don't work.
