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
