Why does the proxy work in the Telegram client but not in the Python bot?

Question

Python

There is a simple bot in Python for Cart,

the code

import telebot
from telebot import apihelper

token = '' #вписан верный

apihelper.proxy = {'https':'socks5://166.62.43.205:49683'}


bot = telebot.TeleBot(token)

@bot.message_handler(commands=['start'])
def start_message(message):
    bot.send_message(message.chat.id, 'Привет, ты написал мне /start')

@bot.message_handler(content_types=['text'])
def send_text(message):
    if message.text.lower() == 'привет':
        bot.send_message(message.chat.id, 'Привет, создатель')
    elif message.text.lower() == 'пока':
        bot.send_message(message.chat.id, 'Прощай, создатель')

bot.polling()

However, he cannot reach the Telegram servers. Sometimes it happens that the connection will appear, but literally for 10 seconds, and then rarely.
How to treat it?
