@MihaZupan i cant get the messages sent to my bot when my bot is offline , i can only get the messages that has been send to my bot when my bot in online

You will get all available messages when you start the bot. If the downtime is prolonged you are not guaranteed to get any messages from before.
The bot should be "online" all the time to receive messages.
