DataStore refusing to load data?

I have tried numerous ways to get it to work, unsure if it is a bug or not but can someone help me please The error I keep receiving is 19:29:22.015 - 502: API Services rejected request with error: HTTP 0 (HTTP 403 (HTTP/1.1 403 Forbidden)) Here is the script if you want to have a look at it.

local data = game:GetService("DataStoreService")
local datastore = data:GetDataStore("RebornDataInitialiser")

game.Players.PlayerAdded:Connect(function(player)
	local userid = tostring(player.userId)
	local data1 = Instance.new("Folder")
	data1.Name = "Data"
	data1.Parent = player
	local xp = Instance.new("IntValue")
	xp.Name = "XP"
	xp.Value = 0
	xp.Parent = data1
	local level = Instance.new("IntValue")
	level.Name = "Level"
	level.Value = 0
	level.Parent = data1
	local saving = datastore:GetAsync(userid)
	
	if saving then
		level.Value = saving[1]
		xp.Value = saving[2]
	else
		local plr_data = {level.Value, xp.Value}
		datastore:SetAsync(userid, plr_data)
		
		game.Players.PlayerRemoving:Connect(function(player)
			local id = tostring(player.userId)
			local plr_data2 = {player.Data.Level.Value, player.Data.XP.Value}
			datastore:SetAsync(id, plr_data2)
		end)
	end
end)
