having issues with hard gel & tips!!!

hey guys. i’ve been having issues with hard gel and tips. i’ve tried luminary & ibd hard gel, as well as both kiss glue and another generic glue i can’t remember the name of. but anytime i use hard gel with tips glued on, they start to pop off within like 48 hours! i’m so confused. is it just not recommended to use hard gel with tips? is it my glue? what do i need to do, because it’s humiliating having a client trust me and doing a beautiful set only for it to pop off in 2 days!!
