The pads must close properly to get the lowest notes.
Are you certain that your flute is in great playing condition?
Then, I'd suggest practicing your notes down to low C.
Either chromatically from low G or in some scale.
> G, F, E, D, C.
If you lose the tone on a note them this may be a pad problem or
your fingers aren't accustomed to proper finger action.
You also have to keep your fingers centered on the finger holes or
the centers of the keys.
IF you even touch any of these by accident or from bad hand position:
the Ab key,
the two D/D# trill keys
or the D#/Eb key .....
then the low C will not sound.
I hope that this helps.

If you take lessons, have your teacher test your flute for leaks, or if you have access to some other flutes you could play for a minute or two (school flutes, friend's flutes, etc.) and see if you can play low C on that flute. If you can, then your flute probably has a problem. I had the same problem on my old flute, and playing some other flutes made me aware of the problem with it. I took it in for a service and the problem was fixed, and I later replaced it for other reasons. IF your flute does not have a problem, then make sure you aren't accidentally hitting any keys you shouldn't be. If your flute doesn't have a problem and you aren't hitting any extra keys, try aiming the airstream slightly downwards more into the flute, and drop your jaw and move it slightly backwards. I hope this helps!
