I'm trying to catch an exception telebot.apihelper.ApiTelegramException: A request to the Telegram API was unsuccessful. Error code: 502. Description: Bad Gateway:

def start_polling(self):
        """Start bot polling"""
        while True:
            try:
                self.sleep_time += 5  # The time in seconds that we sleep for after each cycle.
                bot_logger.info('Start polling')
                self.bot.polling(timeout=60, long_polling_timeout=60, none_stop=True, skip_pending=True)
            except (ReadTimeout, HTTPError, ConnectionError) as e:
                self.bot.stop_polling()
                bot_logger.debug(f"Connection error: {e}. Retry after {self.sleep_time} seconds")
                bot_logger.error(f'Connection error. Retry after {self.sleep_time} seconds')
                sleep(self.sleep_time)
                continue
            except telebot.apihelper.ApiTelegramException as e:
                self.bot.stop_polling()
                bot_logger.debug(f'Telegram API error: {e}. Connection attempt after {self.sleep_time} seconds.')
                bot_logger.error(f'Telegram API error. Connection attempt after {self.sleep_time} seconds.')
                sleep(self.sleep_time)
                continue
            except Exception as e:
                self.bot.stop_polling()
                bot_logger.debug(f"Unexpected exception: {e}. Unable to perform an automatic restart. Shutdown bot ")
                bot_logger.error("Unexpected exception. Unable to perform an automatic restart. Shutdown bot")
            break

For some reason that I don't fully understand, I am unable to complete the task. Every time an error 502 occurs, a full traceback is generated in the logs:

polling does not raise ApiTelegramException-s. It handle and suppress it.

Use exception_handler of Telebot to pass your handler.
