PythonAnywhere - OSError：[Errno 101] 网络无法访问

Question

这个电报机器人的代码以前可以在 pythonanywhere 上运行，直到有人意外地将其删除，现在尝试再次上传它，但遇到一些错误。我尝试关闭防火墙来修复错误，但我不太熟悉 python，所以不确定代码中是否缺少某些内容或其完全是网络问题，我也不知道如何修复。这是机器人。

我尝试关闭我的防火墙来修复错误，但我不太熟悉Python，所以不确定代码中是否缺少某些内容或其完全是网络问题，我也不知道如何修复。我访问了多个论坛均无济于事，非常感谢您的帮助。顺便说一句，我在 pythonanywhere 上使用免费帐户，但这以前不是问题。
