Title: Building a Telegram Bot with Python, Flask, and Ngrok Webhook: Troubleshooting the "Bot Stops Answering" Issue
Telegram bots are a powerful way to automate tasks and engage with users on the Telegram messaging platform. In this tutorial, we'll guide you through creating a Telegram bot using Python, Flask, and Ngrok for setting up a webhook. We'll also address a common issue where the bot stops responding to messages even though the script continues to receive post messages.

Update your Flask script to handle Telegram webhook requests.
If your bot stops responding to messages, but the Flask app still receives post messages, it could be due to various reasons:
Ngrok Session Timeout:

Flask Debug Mode:
If running the Flask app in debug mode (app.run(debug=True)), it may cause issues. Disable debug mode in production.
Check Bot Token:
Ensure that the bot token in your script matches the one provided by BotFather.
By following these steps and troubleshooting tips, you can create a robust Telegram bot using Python, Flask, and Ngrok as a webhook, ensuring it remains responsive to user messages.
