Ok, a few things are wrong.
You need to get the hot side hotter... 88-92 hot side, 78-82 cool side. No part of the cage should ever get above 95 or lower than 75 degrees.
Your cage is way too big. Do you have more than one in the same cage? That is a bad idea.
Half log hides aren't very good, they provide very little security for the snake. Enclosed hides are much better.
