Telegram bot on Heroku runs for 60 seconds. Why?

Question

Python

This is my first time deploying a bot to Heroku.
There is the simplest bot that can respond to /start /info commands.
In the root folder, the file with the bot itself is called - bot.py
- an empty file __init__.py
- Procfile with the text:
web: python3 bot.py
- requirements.txt with the text (created using pip freeze >> requirements.txt ):

certifi==2018.4.16
chardet==3.0.4
Click==7.0
Flask==1.0.2
idna==2.6
itsdangerous==1.1.0
Jinja2==2.10
MarkupSafe==1.1.0
pyTelegramBotAPI==3.6.4

urllib3==1.22
virtualenv==16.4.0

bot.py

#!/usr/bin/python
# -*- coding: utf-8 -*-

import telebot
import os
from flask import Flask, request
import logging

bot = telebot.TeleBot("593642481:AAEuoLHI.....")

@bot.message_handler(commands=['start'])
def handle_text(message):
    user_markup = telebot.types.ReplyKeyboardMarkup(True,False)
    user_markup.row('/start','/info')
    start_text = str('Привет, '+message.from_user.first_name+'!\nЯ бот на Heroku.')
    bot.send_message(chat_id=1154965888, text=start_text, parse_mode='Markdown')

if "HEROKU" in list(os.environ.keys()):
    logger = telebot.logger
    telebot.logger.setLevel(logging.INFO)

    server = Flask(__name__)
    @server.route("/bot", methods=['POST'])
    def getMessage():
        bot.process_new_updates([telebot.types.Update.de_json(request.stream.read().decode("utf-8"))])
        return "!", 200
    @server.route("/")
    def webhook():
        bot.remove_webhook()
        bot.set_webhook(url="https://test-new-new.herokuapp.com") 
        return "?", 200
    server.run(host="0.0.0.0", port=os.environ.get('PORT', 60))
else:
    bot.remove_webhook()
    bot.polling(none_stop=True)

According to the instructions, I download everything and do the deploy. As a result, the bot is launched. Works great for 1 minute. And then silence...
In the logs it says this:

Tell me where to dig? What am I doing wrong?

Answer 1

Use webhook: How to setup webhook for Telegram bot (python3 + pyTelegramBotAPI) on Heroku hosting?
And use port 5000 and not 60:
This is how it works for me:

import telebot
import os
from flask import Flask, request


bot = telebot.TeleBot("593642481:AAEuoLHI.....")

server = Flask(__name__)


@bot.message_handler(commands=['start'])
def handle_text(message):
    user_markup = telebot.types.ReplyKeyboardMarkup(True,False)
    user_markup.row('/start','/info')
    start_text = str('Привет, '+message.from_user.first_name+'!\nЯ бот на Heroku.')
    bot.send_message(chat_id=1154965888, text=start_text, parse_mode='Markdown')


@server.route('/' + tokenBot.TOKEN, methods=['POST'])
def getMessage():
    bot.process_new_updates([telebot.types.Update.de_json(request.stream.read().decode("utf-8"))])
    return "!", 200

@server.route("/")
def webhook():
    bot.remove_webhook()
    bot.set_webhook(url='https://test-new-new.herokuapp.com/' + tokenBot.TOKEN)
    return "!", 200


if __name__ == '__main__':
    server.debug = True
    server.run(host="0.0.0.0", port=int(os.environ.get('PORT', 5000)))

Answer 2

dig here:
Heroku waits for the process to open the port and listen to it, the process apparently does not, and Heroku considers the launch to be unsuccessful.
You need to either find in Heroku where this behavior is configured and disable the check, or set $PORT to the desired port if the process is listening on some port.
