Remote event not firing for some reason?

So I was making my own chat and bubble chat system and I tried to use remote event to fire when the player talks. However, the remote event did not fire and it didn't show anything on the server and client. I did try to search on how to fix it but none of these answers seemed to work for me. Feel free to ask any questions.

ServerScriptService script:

game.ReplicatedFirst.ChatMessage.OnServerEvent:Connect(function(p, msg)
	local ChatGUI = p.Character:WaitForChild("BubbleChatUI")
	spawn(function()
		while wait(1) do
			Timer = Timer - 1
			if Timer < 0  then
				Timer = 0
				ChatGUI.Enabled = false
			end
		end
	end)
	print("Chat message detected.")
	msg = game:GetService("Chat"):FilterStringForBroadcast(msg, p)
	ChatGUI.Enabled = true
	local val = Instance.new("StringValue", workspace.chatMessages)
	val.Name = p.Name
	val.Value = msg
	ChatGUI.MessageLabel.TextLabel.Text = msg
	Timer = 4
end)

TextBox localscript:

script.Parent.FocusLost:Connect(function(EnterPressed)
	if EnterPressed then
		game.ReplicatedFirst:WaitForChild("Events").ChatMessage:FireServer(script.Parent.Text)
		script.Parent.Text = ""
	end
end)
