Why is my textbox.FocusLost not working? [Answered by me]

Im making an instagram story question in roblox, and when the part the player answer the question, focus lost is bugging. I don't want to use any button I just want to use focuslost here's the script

game.Players.PlayerAdded:Connect(function(plr)
	game.ReplicatedStorage.askquestion.OnServerEvent:Connect(function(player,question)
		player.PlayerGui.ScreenGui.QNAANSWER.Visible = true
		player.PlayerGui.ScreenGui.QNAANSWER.Frame.TextLabel.Text = question
		print(player.PlayerGui.ScreenGui.QNAANSWER.Frame.TextLabel.Text)
		print(player.PlayerGui.ScreenGui.QNAANSWER.Frame.TextBox.Text)
		print(plr.Name)
		player.PlayerGui.ScreenGui.QNAANSWER.Frame.TextBox.FocusLost:Connect(function()
			print('ok')
		end)
		plr.PlayerGui.ScreenGui.QNAANSWER.Frame.TextBox.FocusLost:Connect(function()
			print('ok')
		end)
	end)
end)

as you might've guessed it's from a script not a local script, placed in the serverscriptservice no errors in output. This is how the explorer looks like

why are you handling guis on the server, you shouldn't handle guis on the server, also there is no need for playerAdded event, just get a question using a remote function from the client to the server, for example

-- Server
local questions = {{questionText = "What is 1 + 1", answer = 2}, {questionText = "Never gonna?", answer = "give you up"}} -- I don't use instagram so I don't know what the story question system is

local function createQuestion(text, answer)
	local newQuestion = {}
	newQuestion.questionText = text or ""
	newQuestion.answer = answer
	local index = questions[#questions+1]
	questions[index] = newQuestion
	return index
end

local function getQuestion(index)
	return questions[index]
end

local function getRandomQuestion()
	local rand = Random.new(os.time())
	local question = questions[rand:NextInteger(1, #questions)]
	return question	
end

game.ReplicatedStorage.GetQuestion.OnServerInvoke = function(player)
	local question = getRandomQuestion() -- Ask a random question or whatever, you can even send the same question e.g return questions[1]
	return question
end)

-- Client
-- Instead of firing askquestion event
local question = game.ReplicatedStorage.GetQuestion:InvokeServer()

if (question) then
	local questionGui = player.PlayerGui:WaitForChild("ScreenGui") -- "player" should be "game.Players.LocalPlayer"
	local qnaAnswer = questionGui:WaitForChild("QNAANSWER")

        qnaAnswer.Visible = true
        qnaAnswer.Frame.TextLabel.Text = question.questionText
        print(qnaAnswer.Frame.TextLabel.Text)
        print(qnaAnswer.Frame.TextBox.Text)
        print(plr.Name)

	qnaAnswer.Frame.TextBox.FocusLost:Connect(function(hasPressedEnter)
            -- Check whatever
        end)
        plr.PlayerGui.ScreenGui.QNAANSWER.Frame.TextBox.FocusLost:Connect(function(pressedEnter)
             -- code here
        end)
end

Fixed this by making another remote event and used :FireClient()
