从crontab启动而不是手动启动时出现SSL错误发生了什么问题？

Question

我有一个小电报机器人在树莓皮上运行。它使用aiogram框架，该框架使用asyncio和aiohttp。当通过python bot.py启动bot时，一切正常。但是如果我将@reboot <path to python> <path to bot.py> > bot.py.log添加到pi的crontab中，日志会给出以下错误：

Aiohttp client throws an error: ClientConnectorError: Cannot connect to host api.telegram.org:443 ssl:default [Connect call failed ('2001:67c:4e8:f004::9', 443, 0, 0)]

我不明白为什么这个错误只发生在通过crontab启动时，而不是手动启动时。我在pi的控制台中粘贴了用于crontab的精确命令，没有得到错误。你知道发生了什么事以及如何解决这个问题吗

编辑： 由于我越来越相信这可能是python和aiohttp的问题，下面是完整的错误堆栈：
