Header guard names

I wanted to add header guards to my header files (#ifndef, …) and the style warning in my vs code told me to name them e.g. INCLUDE_WORDLE_H_, which then passed the style pub test on my local end. But that exact header guard failed on the server-side public test, which demanded PROG2_INCLUDE_WORDLE_H_, which then not only fails my local pub test but also fails the server-side one as well, demanding i name it the exact thing i named it.

So my question is, what exactly should the header guard look like to pass the style test, or should we not use them?
