Hi there and welcome to the forum!
Here's a link on the care and such:

And here is one I found right on our forum
https://scorpionforum.darkbb.com/caresheets-f29/pandinus-imperator-and-most-heterometrus-spp-tropical-forest-scorpions-t38.htmThe first one is pretty good and even talks about molting.
Make sure your conditions match with what the care sheets say.
The main problem with molting seems to be the humidity, so you want to keep that high.
Often times during molting, people increase both the temperature and the humidity to help the scorp molt.
You can increase humidity by dumping water onto the substrate.
Usually forest scorpions don't have much of a problem molting--it's the dry desert ones that usually have trouble.
Also, I'd remove the artificial rock background if possible. It's probably not doing the scorpion any good fall 1.5 feet like that and continuously, too.
Good luck with your scorpion, they're one of my favorites!
Do check out the Breeding Reports section on the forum and look for anything Heterometrus; very interesting stuff to read and look at. Great pics in them as well.
