502: API Services rejected request with error. HTTP 403 (Forbidden), does anybody know a fix?

So, I'm trying to make a DataStore for cash in a game. For some reason, even after enabling API Services in the Studio settings, I still get the error message:

"502: API Services rejected request with error. HTTP 403 (Forbidden)"

(Proof of enabling API Services: https://prnt.sc/t1l1p7)

Here is my code:

local DataStoreService = game:GetService("DataStoreService")
local ReplicatedStorage = game:GetService("ReplicatedStorage")
local Players = game:GetService("Players")

local cashDataStore = DataStoreService:GetDataStore("cashDataStore")

game.Players.PlayerAdded:Connect(function(player)
	cashCounter = player.PlayerGui:WaitForChild("StarterScreenUI").sideGui.Frame.cash
	
	local cashData
	local success, errormessage = pcall(function()
		cashData = cashDataStore:GetAsync(player.UserId.."-cash")
	end)
	
	if success then
		cashCounter.Text = "$"..cashData
	else
		cashDataStore:SetAsync(player.UserId.."-cash",200)
		cashData = cashDataStore:GetAsync(player.UserId.."-cash")
		cashCounter.Text = "$"..cashData
	end
	
	return cashCounter
end)

game.Players.PlayerRemoving:Connect(function(player)
	local success, errormessage = pcall(function()
		cashDataStore:SetAsync(player.UserId.."-cash",cashCounter.Text)
	end)
	
	if success then
		print("Success")
	else
		warn(errormessage)
	end
end)

ReplicatedStorage.Events.PurchaseSaveEvent.OnServerEvent:Connect(function()
	
end)

while wait(2) do
	cashData = cashData + 1
	cashCounter.Text = "$"..cashData
	print(cashCounter.Text)
end
