502: API Services rejected request with error: HTTP 0 (HTTP 403 (HTTP/1.1 403 Forbidden)) ?

When I tried running my script that made stats for a character and made datastores for each stat, this error came up:

502: API Services rejected request with error: HTTP 0 (HTTP 403 (HTTP/1.1 403 Forbidden))

I removed the line, but it happened to each :GetAsync piece of the script

I wrote this entire script. I hope it was not for nothing.

local DataStoreService = game:GetService("DataStoreService")

local healthMaxData = DataStoreService:GetDataStore("healthMaxData")
local healthPresentData = DataStoreService:GetDataStore("healthPresentData")
local staminaMaxData = DataStoreService:GetDataStore("staminaMaxData")
local staminaPresentData = DataStoreService:GetDataStore("staminaPresentData")
local hungerMaxData = DataStoreService:GetDataStore("hungerMaxData")
local hungerPresentData = DataStoreService:GetDataStore("humgerPresentData")

game.Players.PlayerAdded:connect(function(plr)
	
	local statsFolder = Instance.new("Folder", plr)
	statsFolder.Name = "statsFolder"
	
	local healthMax = Instance.new("IntValue", statsFolder)
	healthMax.Name = "healthMax"
	healthMax.Value = healthMaxData:GetAsync(tostring(plr.UserId)) or 100 -- right here is where the first error occured
	
	local healthPresent = Instance.new("IntValue", statsFolder)
	healthPresent.Name = "healthPresent"
	healthPresent.Value = healthPresentData:GetAsync(tostring(plr.UserId)) or healthMax.Value
	
	local staminaMax = Instance.new("IntValue", statsFolder)
	staminaMax.Name = "staminaMax"
	staminaMax.Value = staminaMaxData:GetAsync(tostring(plr.UserId)) or 100	
	
	local staminaPresent = Instance.new("IntValue", statsFolder)
	staminaPresent.Name = "staminaPresent"
	staminaPresent.Value = staminaPresentData:GetAsync(tostring(plr.UserId)) or staminaMax.Value	
	
	local hungerMax = Instance.new("IntValue", statsFolder)
	hungerMax.Name = "hungerMax"
	hungerMax.Value = hungerMaxData:GetAsync(tostring(plr.UserId)) or 100
	
	local hungerPresent = Instance.new("IntValue", statsFolder)
	hungerPresent.Name = "hungerPresent"
	hungerPresent.Value = hungerPresentData:GetAsync(tostring(plr.UserId)) or hungerMax.Value
	
	plr.CharacterAdded:connect(function(char)
		if char:FindFirstChild("Humanoid") ~= nil then
			local humanoid = char.Humanoid
			humanoid.Health.Changed:connect(function()

	end)

	end)
end)

game.Players.PlayerRemoving:connect(function(plr)
	healthMaxData:SetAsync(tostring(plr.UserId), plr.statsFolder:FindFirstChild('healthMax').Value)

Can anyone help me?
