Custom cursor works in a SP test world, but not in a MP one. What am I doing wrong?

This seem to work perfectly when I play in a test world, however; it does not work at all when I am testing the server with multiple people. What am I doing wrong?

Script in Workspace

--Normal script

local mouse = game.Players.LocalPlayer:GetMouse()

--Change the cursor when hovering over an object
script.Parent.MouseHoverEnter:connect(function(player)
	mouse.Icon = "http://www.roblox.com/asset/?id=652181258"
	
end)

--Change the cursor when leaving the object
script.Parent.MouseHoverLeave:connect(function(player)
	mouse.Icon = "http://www.roblox.com/asset/?id=652178724"
end)

Localscript in StarterGui

--Localscript in StarterGui > ScreenGui
local mouse = game.Players.LocalPlayer:GetMouse()
mouse.Icon = "http://www.roblox.com/asset/?id=652178724"

You cannot access the Mouse object from the server. Execute all your code on the client for this to work.

--Localscript

local mouse = game.Players.LocalPlayer:GetMouse()

--Change the cursor when hovering over an object
script.Parent.MouseHoverEnter:connect(function(player)
	mouse.Icon = "http://www.roblox.com/asset/?id=652181258"
end)

--Change the cursor when leaving the object
script.Parent.MouseHoverLeave:connect(function(player)
	mouse.Icon = "http://www.roblox.com/asset/?id=652178724"
end)
