我按照文档中的每一步操作，但仍然无法在本地连接。目前，我使用的是 Mozilla 77.0.1（64 位）版本。因此，我network.websocket.allowInsecureFromHTTPS按照特定浏览器设置中的说明启用了该功能。即使我--no-browser按照Jupyter HTTP-over-WebSocket故障排除建议尝试了该标志。我究竟做错了什么？

任何进一步的帮助将不胜感激。

Answer 1

有一些原因，例如

1. 您的浏览器扩展（删除/停止所有扩展，因为它们阻止了您）
2. 使用

jupyter笔记本 --NotebookApp.allow_origin='https://colab.research.google.com' \ --port=9090 --no-browser
