The camera settings shouldn't matter, but I don't use a D5x00, so I don't know what different settings I might have.
Make sure of that:
- the flashes are in slave radio mode
- the trigger and the flashes are on the same radio channel
- the group to which the flashes are assigned is set to trigger on the trigger
If all this was already true, try turning everything off and then back on again in this sequence: it blinks, then shoots, then the camera. (Also make sure the shutter is already in the camera before turning on everything.)
