Proximity Trigger not working anymore?

My proximity trigger used to work. It was always working but now, it doesn't work anymore.

I searched online but that didn't help so now I have to do this.

Code:

( Its a big one. Scroll down until you see, .Triggered )

local ChatService = game:GetService("Chat")
local ServerStorage = game:GetService("ServerStorage")
local Remotes = game:GetService("ReplicatedStorage").Remotes
local Rep = game:GetService("ReplicatedStorage")

local talkpart = script.Parent.Parent

local AIstarted = false
local connection
local connection2
local connection3

local shownPassport = false
local conversationgoingon = false

local StandClass = 'FC'

function nameGenerator(gender)
	local BoyNames = {
		"Dan", "Jonathan", "James", "Jack", 'Tom', "Lorenzo", "Philip", "Kacper", "Daryl", "Timmothy", "Bob", "Ben", "Walsher", "Rod", "Sean"
	}
	local GirlNames = {
		"Mary", 'Theresa', "Felicia", "Karina", "Lia", "Amanda", "Alexandra", "Penelope", "Catherine", "Ellie", "Daisy"
	}
	
	if gender == "Boy" then
		return BoyNames[math.floor(math.random(1, #BoyNames))]
	end
	if gender == "Girl" then
		return GirlNames[math.floor(math.random(1,#GirlNames))]
	end
end

local chosenName = nameGenerator("Boy")

function giveBoardingPass(plr)
	for i, v in pairs(ServerStorage.BoardingPasses:GetChildren()) do
		if v.TypeOfClass.Value == StandClass then
			local clonedBP = v:Clone()
			clonedBP.Parent = plr.Backpack
		end
	end
end

script.Parent.Triggered:Connect(function(plr)
	print("triggered")
	if conversationgoingon == false then
		if plr.Backpack:FindFirstChild("Ticket") == nil then
			conversationgoingon = true
			ChatService:Chat(talkpart, "Greetings, call me " .. chosenName .. ". Please show your passport for this flight." , Enum.ChatColor.Green)
			plr.Backpack.Passport.Equipped:Connect(function()
				if shownPassport == false then
					shownPassport = true
					wait(1)
					ChatService:Chat(talkpart, "Thank you, " .. plr.DisplayName .. "." , Enum.ChatColor.Green)
					wait(3)
					ChatService:Chat(talkpart, "Now, have you booked already or not	?" , Enum.ChatColor.Green)
					connection = plr.Chatted:Connect(function(msg)
						--- Tier 1 ---
						local Message = string.lower(msg)
						if string.find(Message, "yes")  ~= nil then

						elseif string.find(Message, "no") then

							wait(2)
							ChatService:Chat(talkpart, "You are flying with First Class for this flight. Please pay $250. If you have any special cards. Please show now. Say 'Okay' to start transaction." , Enum.ChatColor.Green)
							connection2 = plr.Chatted:Connect(function(msg2)
								--- Tier 2 (Transaction) ---
								connection:Disconnect()
								local Message2 = string.lower(msg2)
								print("Said " .. Message2)

								if string.find(Message2, "okay") then 
									connection2:Disconnect()
									print("paid")
									plr.leaderstats.Cash.Value = plr.leaderstats.Cash.Value - 250
									if plr.leaderstats.Cash.Value > 0 then
										wait(2)
										ChatService:Chat(talkpart, "Your transaction is approved. Here is your boarding pass. And the departure gate is " ..  require(Rep.GameValues).gate .. ".", Enum.ChatColor.Green)
										giveBoardingPass(plr)
										
										shownPassport = false
										conversationgoingon = false
									else
										plr.leaderstats.Cash.Value = plr.leaderstats.Cash.Value + 250
										ChatService:Chat(talkpart, "Your transaction is declined. Try again with more cash, or fly with a different class.", Enum.ChatColor.Green)
										
										shownPassport = false
										conversationgoingon = false
										
									end
								else
									ChatService:Chat(talkpart, "I don't understand you. Please state your answer differently." , Enum.ChatColor.Green)
								end
							end)
						else
							ChatService:Chat(talkpart, "I don't understand you. Please state your answer differently." , Enum.ChatColor.Green)
						end
					end)
				end
			end)
		else
			ChatService:Chat(talkpart, "Greetings. Are you here for a refund?" , Enum.ChatColor.Green)
			connection3 = plr.Chatted:Connect(function(msg3)
				local Message3 = string.lower(msg3)

				if string.find(Message3, "yes") then
					connection3:Disconnect()
					ChatService:Chat(talkpart, "Here is your refund." , Enum.ChatColor.Green)
					wait(1.5)
					ChatService:Chat(talkpart, "Unfortunately, you don't get the full amount of the price you paid." , Enum.ChatColor.Green)
					plr.leaderstats.Cash.Value = plr.leaderstats.Cash.Value + 175

					shownPassport = false
