Why won't my join log/chat log script work in the real game?

basicly when you join it puts whjo joins and what they said in the discord channels. It works in studio and studio testing with the server but not the actualy real game for some reason.

Discord API

--[[
	Discord - Roblox hookup

	Do not touch this script.
--]]

local webHook = {}
webHook.__index = webHook

function webHook.new(id,key) 
	local mt = setmetatable({id=id,key=key}, webHook) 
	return mt
end

function webHook:post(config,host)
	local data = nil
	local success = pcall(function()
		data = game:GetService("HttpService"):JSONEncode(config)
	end)
	if not success then warn("Webhook can't be converted to JSON") return end
	game:GetService("HttpService"):PostAsync("https://discordapp.com/api/webhooks/"..self.id.."/"..self.key,data)
end

return webHook

local APIModule  = require(script.Parent)



local newWebHook = APIModule.new("--Cannot Expose--","--Cannot Expose--")

game.Players.PlayerAdded:Connect(function(Player)
newWebHook:post{
			username = "Player",
			content = "**" .. Player.Name .. "** has joined the server"
		}
end)

Chat Logger

local APIModule  = require(script.Parent)

local newWebHook = APIModule.new("--Cannot Expose--","--Cannot Expose--")

game.Players.PlayerAdded:Connect(function(Player)
	Player.Chatted:Connect(function(msg)
		newWebHook:post{
			username = Player.Name,
			content = msg
		}
	end)	
end)

Is there any fix?
