这是我的代码：

import asyncio
import aiohttp


async def main():
    loop = asyncio.get_event_loop()
    url = "https://stackoverflow.com/"

    async with aiohttp.ClientSession(loop=loop) as session:
        async with session.get(url, timeout=30) as resp:
            print(resp.status)

asyncio.run(main())

如果我在计算机上运行它，一切正常，但是如果我在pythonanywhere上运行，则会出现此错误：

The above exception was the direct cause of the following exception:

我不知所措不是吗？我正在使用python3.8运行两个文件。

我也尝试了其他网址，它们有相同的问题

我是否需要添加更多详细信息？
