Why does the bot crash with an error?

Question

Python

I followed this instruction https://qsy.by/telegram-bot-na-python-chast-2-pych... , starting from the line, we will start writing code.
Here is the code

import telebot
from telebot import apihelper
TOKEN = '836764194:AAHd4h                           Kv1HVvIl1g'
apihelper.proxy = {'http':'http://171.255.192.118:8080'}
bot = telebot.TeleBot(TOKEN)
@bot.message_handler(commands=['start'])
def start(message):
    sent = bot.send_message(message.chat.id, 'Как тебя зовут?')

bot.polling()

Here is what is installed

Here is the error itself

Proxy also does not work

Answer 1

import telebot
from telebot import apihelper

bot = telebot.TeleBot(TOKEN)
apihelper.proxy = {'https': 'socks5h://user:[email protected]:1080'}

pyTelegramBotAPI
in socks5:// documentation, try socks5 h ://

Answer 2

Perhaps due to the fact that the provider blocked access to the telegram.
