Just make sure you temps are correct about (give or take a degree or two) 90 warm area and about 80 cool with an ambient air temp between 79-85. Snakes need heat to digest (an everything else) and they need to regulate their temps by moving between warm and cool areas. If the temps are wrong they will not digest and will not eat because of that.
Prey off temp as well could be a cause or not feeling secure. You might try adding some more cover to the enclosure. Do you have 2 identical hides? If you do try adding a fake plant or ever a few balls of newspaper. They are quite vulnerable after feeding and if they do not feel secure they also will not eat.
