How can i make my datastore for bans work? Am i missing something?

Just wanted to make a ban datastore today, and i feel like i'm missing something on the code. Seems to not work in roblox with api services enabled. <--- Problem

local DataStore = game:GetService("DataStoreService")
local ds1 = DataStore:GetDataStore("BanDataStore")

game.Players.PlayerAdded:Connect(function(player)
    local folder = Instance.new("Folder",player)
    folder.Name = "PlayerValues"

    local banvalue = Instance.new("BoolValue",folder)
    banvalue.Value = false
    banvalue.Name = "BanValue"

end)


        --SetAsync.Ban
    game.Players.PlayerRemoving:Connect(function(player)
    if player.PlayerValues.BanValue.Value == true then
        ds1:SetAsync(player.UserId, player.PlayerValues.BanValue.Value)


--BanCheck
ds1:GetAsync(player.UserId, player.PlayerValues.BanValue.Value)
        if player.PlayerValues.BanValue.Value == true then
            player:Kick("Banned.")
        end
        end
        end)
