HTTP 403 (Forbidden)

Hello, I have a feedback button in my game that normally accesses a website which sends feedback to a bot on Discord, but I just tested it and it says HTTP 403. How do I fix this?

It says the error is on line 23.

local Player = game.Players.LocalPlayer
local maxCharacters = 300
local RS = game:GetService("ReplicatedStorage")
local db = false
local feedbackMain = script.Parent.Parent.FeedbackFrame

feedbackMain.CharactersLeft.Text = maxCharacters - #feedbackMain.InputBox.Input.Text.. " Characters Left"
feedbackMain.InputBox.Input.Changed:Connect(function()
	feedbackMain.CharactersLeft.Text = maxCharacters - #feedbackMain.InputBox.Input.Text.. " Characters Left"
	if maxCharacters - #feedbackMain.InputBox.Input.Text < 0 then
		feedbackMain.CharactersLeft.TextColor3 = Color3.fromRGB(255,50,50)
	else
		feedbackMain.CharactersLeft.TextColor3 = Color3.fromRGB(255,255,255)
	end
end)

feedbackMain.MessageButton.MouseButton1Click:Connect(function()
	if not db and maxCharacters - #feedbackMain.InputBox.Input.Text > 0 then
		db = true
		local msg = feedbackMain.InputBox.Input.Text
		feedbackMain.InputBox.Input.Text = "Delivering Message..."
		feedbackMain.InputBox.Input.TextEditable = false
		local response = RS:WaitForChild("SendFunction"):InvokeServer(msg)
		feedbackMain.InputBox.Input.Text = ""
		feedbackMain.InputBox.Input.PlaceholderText = response
		wait(5)
		if feedbackMain.InputBox.Input.PlaceholderText == response then
			feedbackMain.InputBox.Input.TextEditable = true
			feedbackMain.InputBox.Input.PlaceholderText = "Enter your feedback here!"
		end
		wait(30)
		db = false
	end
end)

script.Parent.MouseButton1Click:Connect(function()
	feedbackMain.Visible = not feedbackMain.Visible
end)

Other script in case its needed:

local webhook = "https://webhook.lewisakura.moe/api/webhooks/1175217104849473597/7HWSDE1IPlDDbRTgFejZHQcTz8LmrIevoorH1COh_Piw_wbrbHsfg8U1xasl5EM4LUCL/queue"
local SendFunction = game.ReplicatedStorage.SendFunction 
local HTTP = game:GetService("HttpService")

function SendFunction.OnServerInvoke(Player, msg)
	local payload = HTTP:JSONEncode({
		content = msg,
		username = Player.Name.." ("..Player.UserId..") sent feedback!"
	})

	HTTP:PostAsync(webhook, payload)
	return "Feedback recieved!"
end

Did Roblox break this? Thank you!

When I just visit your webhook, I’m not met with a 403. I would recommend visiting the site, and double checking your registration with them: https://webhook.lewisakura.moe/.
