在 aiogram3 (pythonanywhere) 上托管机器人时出错

我正在尝试在pythonanywhereaiogram3托管上安装电报机器人。但启动时出现错误：。ClientConnectorError: Cannot connect to host api.telegram.org:443 ssl:default [Network is unreachable]

完整错误：

During handling of the above exception, another exception occurred:

我查看了其他论坛，他们说您需要使用不同的代理服务器，并在以下位置指定Bot()：

bot = Bot(token='...', proxy='http://proxy.server:3128')

但班级Bot()没有争论proxy，很可能是因为aiogram3

Bot.__init__() got an unexpected keyword argument 'proxy'

还用过图书馆aiohttp-socks。但没有任何结果。
