Heroku Python应用程序(Telegram bot)每月崩溃，请求异常

我在Heroku上部署了两个使用PyTelegramBotApi（我知道不是最好的库）制作的电报机器人。一个重要的区别是：一种是使用线程来周期性地向“订阅者”（大约20人）发送通知。它大约每个月都会崩溃，Heroku控制台中的异常跟踪如下：

2022-01-14T08:00:11.068553+00:00 app[worker.1]:   File "/app/.heroku/python/lib/python3.9/site-packages/telebot/apihelper.py", line 139, in _make_request
2022-01-14T08:00:11.068739+00:00 app[worker.1]:     result = _get_req_session().request(
2022-01-14T08:00:11.068748+00:00 app[worker.1]:   File "/app/.heroku/python/lib/python3.9/site-packages/requests/sessions.py", line 542, in request
2022-01-14T08:00:11.068983+00:00 app[worker.1]:     resp = self.send(prep, **send_kwargs)
2022-01-14T08:00:11.068994+00:00 app[worker.1]:   File "/app/.heroku/python/lib/python3.9/site-packages/requests/sessions.py", line 655, in send
2022-01-14T08:00:11.069233+00:00 app[worker.1]:     r = adapter.send(request, **kwargs)
2022-01-14T08:00:11.069242+00:00 app[worker.1]:   File "/app/.heroku/python/lib/python3.9/site-packages/requests/adapters.py", line 529, in send
2022-01-14T08:00:11.069448+00:00 app[worker.1]:     raise ReadTimeout(e, request=request)
2022-01-14T08:00:11.069478+00:00 app[worker.1]: requests.exceptions.ReadTimeout: HTTPSConnectionPool(host='api.telegram.org', port=443): Read timed out. (read timeout=25)

我没有记录以前的异常跟踪（我的错），但我记得它看起来几乎一样（最近的异常是ReadTimeout）。此外，我的任何脚本都没有出现在这个跟踪中（这让我觉得它是不完整的，由于一些Heroku日志控制台错误）。我自己不直接使用requests模块。而且它绝对不可能是由dyno睡眠引起的，因为我只使用worker dyno（它从不睡觉）。这个机器人和没有崩溃的机器人都使用Heroku Postgres。有什么想法可以导致这个异常吗？
编辑：完整的异常跟踪我不小心在调试模式下，而在我的机器上测试的东西：

我已经找到了一种方法，至少可以让机器人继续工作。小心：这可能不适合您的应用程序（在您的情况下，在特定异常后直接重新启动可能会损坏数据或破坏其他东西）。在主文件中，我做了这个构造，它基本上是在一个未处理的异常之后重新启动bot，否则就会停止bot：

def exception_handler(count: int = 0):
    """Relaunching bot unless exceptions occur more than 2 times a day 
(script is reset daily on Heroku)"""
    if count < 3:
        if count > 0:
            print("An exception occurred, relaunching . . .")
            time.sleep(5)
        try:
            deadliner0307()  # bot main function with (bot.polling starts there)
        except Exception as ex:
            count += 1
            # Notifying myself about exception via free Airbrake addon:
            notifier = pybrake.Notifier(project_id=<project_id>,
                                        project_key='<project_key>',
                                        environment='production')
            notifier.notify(ex)
            exception_handler(count)
    else:
        print("Too much exceptions occurred, shutting down . . .")

if __name__ == '__main__':
    exception_handler()
