Scripts, LocalScripts and RemoteEvents work with 1 player in game, but doesn't work with more than 1 player

[light_lanterns (light)]

Script works when 1 player is in the game but doesn’t work when at least 2 players are in the game.

I haven’t found any other topics about this, there might be but I can’t find them so I’m making one.

I made a flashlight LocalScript where the player presses F, their character would show a flashlight on their Left Hand. I used FireServer() for this to connect to a Script on the Character, it all works fine when there is 1 player in the game, but doesn’t work when there is 2 players or more.

I’m not too good at scripting, so I can’t find the issue for this. Nothing shows on output or anything.
Also to mention, I’m using a StarterCharacter that has a Flashlight Inserted on the left arm.

I tried printing to see if the script goes through completely, they all printed correctly but the rest of the script doesn’t work.

Local Script (In StarterPlayerScripts)

local ReplicatedStorage = game:GetService("ReplicatedStorage")
local Players = game:GetService("Players")
local UIS = game:GetService("UserInputService")
local plr = Players.LocalPlayer

local FlashlightTrigger = ReplicatedStorage:WaitForChild("FlashlightTrigger")

UIS.InputBegan:Connect(function(input, gameProccessedEvent)
	if input.KeyCode == Enum.KeyCode.F then
		FlashlightTrigger:FireServer()
		print("Fired to Server")
	end
end)

Script (In Player’s Character)

local ReplicatedStorage = game:GetService("ReplicatedStorage")
local FlashlightTrigger = ReplicatedStorage:WaitForChild("FlashlightTrigger")

local function TriggerFlashlight(player)
	print(player.Name)
	local Flashlight = player.Character["Left Arm"]:FindFirstChild("Flashlight")
	player.Tools.FlashlightEquipped.Value = not player.Tools.FlashlightEquipped.Value
	if player.Tools.FlashlightEquipped.Value == true then
		Flashlight.Transparency = 0
	elseif player.Tools.FlashlightEquipped.Value == false then
		Flashlight.Transparency = 1
	end
	Flashlight.Flash.Enabled = not Flashlight.Flash.Enabled
	print("Script Worked")
end
FlashlightTrigger.OnServerEvent:Connect(TriggerFlashlight)

I hope I put enough information for this.

I believe you should place your script inside ServerScriptService instead of PlayerScripts. You have multiple connections to a signal that’s only meant to be fired once per action. It’s simply canceling itself out.
