Ramp test power target issues

I’ve done 2 ramp test this week, on both occasions I’ve had issues hitting the power targets in the final few steps.

I’m using a Tacx Flux S in erg mode, with small (34t) chainring and middle of cassette (19/21t?) at the back. This is my set up for all TR workouts.

Once I get to the final steps the trainer can not hold the power target, my cadence is still around 90-95 and there’s definitely something left in the tank, but I can’t get it to hold much above 440w. It’s as if I’ve hit a resistance ceiling? any ideas?
