“502: API Services rejected request with error. HTTP 403 (Forbidden)”?

I am trying to make data stores in my game and it keeps popping up with this message, “502: API Services rejected request with error. HTTP 403 (Forbidden)”.

The error occurs on line 25

local DSS = game:GetService("DataStoreService")

local datastore = DSS:GetDataStore("GeneralSaveData", "Players")

function generateDataKey(player)
	local ret = "uid_" .. player.userId
	return ret
end

function generateDataTable(player)
	local dataTable = {
		Coins = game.StarterPack.PlayerAssets.Value.Value,
	}
	return dataTable
end

function saveDataForPlayer(player)
	local key = generateDataKey(player)
	local data = generateDataTable(player)
	datastore:SetAsync(key, data)
end

function loadDataForPlayer(player)
	local key = generateDataKey(player)
	local data = datastore:GetAsync(key)
	inputDataToPlayer(player, data)
end

function inputDataToPlayer(player, data)
	game.StarterPack.PlayerAssets.Value.Value = data.Coins
end

game.Players.PlayerAdded:Connect(function(player)
	loadDataForPlayer(player) -- loads when join
	game.StarterPack.PlayerAssets.Value.Value.Changed:Connect(function()
		saveDataForPlayer(player) -- saves when wins changes
	end)
end)

game.Players.PlayerRemoving:Connect(saveDataForPlayer) -- saves when leave
