Parry system wont register hits?

Im making a sort of RPG game with pvp mechanics and parrying is one of them, parry can only happen with a certain sword. for some reason when the player presses R to parry, the animation plays. but when they get hit nothing happens to the attacker and the player just takes damage like normal

local script inside tool to register if player pressed R, this also registers the hits.

local UIS = game:GetService("UserInputService")
local controls = require(game:GetService("Players").LocalPlayer.PlayerScripts.PlayerModule):GetControls()

local Equipped = false
local Cooldown = false

local CurrentlyParrying = false

local plr = game.Players.LocalPlayer
local Char = plr.Character or plr.CharacterAdded:Wait()

script.Parent.Equipped:Connect(function()
    Equipped = true
    print(Equipped)
end)

script.Parent.Unequipped:Connect(function()
    Equipped = false
    print(Equipped)
end)

UIS.InputBegan:Connect(function(input)
    if Equipped == true and Cooldown == false then
        if input.KeyCode == Enum.KeyCode.R then
            Cooldown = true
            CurrentlyParrying = true
            game.ReplicatedStorage.Parry:FireServer()

            controls:Disable()

            print("Player press R")
            wait(3)
            CurrentlyParrying = false
            controls:Enable()
            wait(5)

            Cooldown = false
        end
    end
end)

Char:WaitForChild("Humanoid").HealthChanged:Connect(function(health)
    Char.HumanoidRootPart.Touched:Connect(function(part)
        if part.Parent:FindFirstChild("Humanoid") then
            print("Attacker is a player")
            local AttackerHumanoid = part.Parent.Humanoid

            game.ReplicatedStorage.ParrySuccess:FireServer()
        end
    end)
end)

ServerScript inside of ServerScript service which registers the events

local ReplicatedStorage = game:GetService("ReplicatedStorage")



ReplicatedStorage.Parry.OnServerEvent:Connect(function(player) --// Parry Event

    local CurrentlyParrying = true

    local Animation = Instance.new("Animation")
    Animation.AnimationId = "rbxassetid://11889172194"

    local Anim = player.Character.Humanoid:LoadAnimation(Animation)
        Anim:Play()
        print("Parry event triggered")
    local char = player.Character
    char.Humanoid:SetAttribute("Mana", char.Humanoid:GetAttribute("Mana") - 25)

    wait(3)
    CurrentlyParrying = false

end)

ReplicatedStorage.ParrySuccess.OnServerEvent:Connect(function(player, AttackerHumanoid)
    local Attacker = game.Players:GetPlayerFromCharacter(AttackerHumanoid.Parent)

    AttackerHumanoid.Health -= 10
    ReplicatedStorage.ParrySuccess:FireClient(Attacker)


end)

LocalScript inside starterCharacter to freeze the attacker upon hitting the person who parried

local controls = require(game:GetService("Players").LocalPlayer.PlayerScripts.PlayerModule):GetControls()

game.ReplicatedStorage.ParrySuccess.OnClientEvent:Connect(function()
    controls:Disable()
    wait(2)
    controls:Enable()
end)
