Script, located in ServerScriptService, works in studio, but does not work in game?

I am trying to make a script that gives a weapon only to me. It only hands me a weapon to a player that has my name. Here is the script:

function Added(plr)
	wait(1)
	if plr.Name == "EliteRayGawnX2" then
		local Katana = script.Katana
		local KatanaClone = Katana:Clone()
		KatanaClone.Parent = plr.Backpack
	end
end
game.Players.PlayerAdded:connect(Added)

It works as intended in studio tests. The weapon but when i actually go to play the game, it does not work. Is it a problem in the script? Or with Roblox?
