It's a machine -or at least a physical entity- it won't magically find a path to the solution if it doesn't have one.
Eg. if you ask it to explain how to build -say- a time machine or a warp drive, it's definitely just going to keep apologizing.
No amount of yelling or abuse will fix this situation.
Sometimes if you try to get it to solve a complex maths or software problem, you might be able to help by applying a few steps of some form of divide and conquer. Either you can do manually yourself, or by suggesting it try to do eg a structured analysis itself. Sometimes it can handle the smaller subproblems ok.
Incidentally this also applies to humans! (Being nicer to humans improves their morale and problem solving ability. Sometimes permanently!)
