UserInputService sometimes works in Server?

I'm using UserInputService and InputBegan to select certain tools in a game I'm creating. The Q, E, A, and D keys all snap the camera to certain positions and work 100% in Studio and in a server. The F, N, S, and R keys don't move the camera, but the InputBegan function is exactly the same (an if statement checking the key pressed and a separate function that fires if true). These 4 keys work 100% in Studio, but never in a server. I even added output printing to the beginning of the InputBegan functions for these letters and the functions themselves don't even fire. Any ideas?
