Teleport script works in studio, not in game. Any help? [SCRIPT in ServerScriptService]

So i'm making a demo game, where whenever you join, it waits 5 seconds, then teleports you to 1 of 2 blocks. Then five seconds later, it does it again. This works in Studio, but not in the Game. Here is the script: (This is a SCRIPT [not local] in ServerScriptService)

while true do
	local Tab = {CFrame.new(26, 0.5, -1); CFrame.new(26, 0.5, -33)}
	local locationselected = Tab[math.random(1, #Tab)]
	wait(.2)
	game.Workspace:WaitForChild(game.Players.LocalPlayer.Name).Head.CFrame = locationselected
	wait()
end

i tried adding a player added event:

game.Players.PlayerAdded:Connect(function(player)
while true do
	local Tab = {CFrame.new(26, 0.5, -1); CFrame.new(26, 0.5, -33)}
	local locationselected = Tab[math.random(1, #Tab)]
	wait(.2)
	game.Workspace:WaitForChild(game.Players.LocalPlayer.Name).Head.CFrame = locationselected
	wait()
end
end)

but thats not working either. Any help?
