I think you have painted yourself into a corner with your selection of component values and frequency. When I simulate the oscillator with very low value resistors it needs at least Ce = 1000 uF before it will oscillate with a 2N2222.
Here are LoZ and HiZ versions that do oscillate at about 20 Hz with a single 2N2222.
Notice the value of Ce required, if I reduce it, the oscillation will not start.
Lo-Z, big capacitors.
Hi_Z, small capacitors.
