Datastore script not loading/saving data with HTTP service?

Ive been at this all day, and there are no errors, it just doesnt load/save. (Im not sure which one). Btw i use http service because it is easier and faster to save alot of data, in the future.

-- [ SERVICES ] --
local Players = game:GetService("Players")
local DataStoreService = game:GetService("DataStoreService")
local Http = game:GetService("HttpService")

-- [ DATASTORES ] --
local Data = DataStoreService:GetDataStore("Data")

Players.PlayerAdded:Connect(function(Player)
	-- Leaderboard
	local leaderstats = Instance.new("Folder")
	leaderstats.Name = "leaderstats"
	leaderstats.Parent = Player
	-- Coins
	local Coins = Instance.new("IntValue")
	Coins.Name = "Coins"
	Coins.Parent = leaderstats
	
	local PlotType = Instance.new("StringValue")
	PlotType.Name = "PlotType"
	PlotType.Parent = Player
	
	-- Player Data
	local UserId = Player.UserId
	
	local PlayerData = {
		Coins = Coins.Value,
		PlotType = PlotType.Value
	}
	
	local Success = false
	local Count = 10
	local CollectedData
	local DecodedData
	while Success == false and Count > 0 do
		local Suc,Err = pcall(function()
			CollectedData = Data:GetAsync(UserId)
			DecodedData = Http:JSONDecode(CollectedData)
		end)
		if Suc then
			Success = true
		else
			Count = Count-1
			warn(Err)
		end
		wait(0.5)
	end
	if Count ~= 0 then
		PlayerData.Coins = DecodedData.Coins
	end
end)
Players.PlayerRemoving:Connect(function(Player)
	local PlayerData = {
		Coins = Player.leaderstats.Coins.Value,
		PlotType = Player.PlotType.Value
	}
	local UserId = Player.UserId
	local Success = false
	local Count = 10
	local EncodedData
	while Success == false and Count > 0 do
		local Suc,Err = pcall(function()
			EncodedData = Http:JSONEncode(PlayerData)
			Data:SetAsync(UserId,EncodedData)
		end)
		if Suc then
			Success = true
		else
			Count = Count-1
			warn(Err)
		end
	end
end)
