尝试停止时出现 Jupyter Notebook 302、403、401 禁止错误和连接被拒绝错误答案

【问题标题】：Jupyter Notebook 302, 403, 401 forbidden error and connection refused error when trying to stop尝试停止时出现 Jupyter Notebook 302、403、401 禁止错误和连接被拒绝错误

【问题描述】：

当我在 Ubuntu 的远程机器上的 conda 环境中打开 jupyter notebook 时，我的终端日志充满了 401 和 403 错误。就像这里的这个问题：Jupyter Creating Notebook failed: FORBIDDEN

然后我尝试了要检查的答案之一：

~$jupyter notebook list

Currently running servers:
http://localhost:8888/?token=0f2ad000db9......
http://0.0.0.0:8899/?token=7aa2a13503d.....

关闭第二个很容易，因为我只是 ssh 到端口 8899 并打开带有关闭链接的浏览器。但是我无法关闭第一个，当我 ssh 进入端口 8888 时，链接在浏览器中不起作用。当我这样做时

~$ jupyter notebook stop
Shutting down server on 8888...
Traceback (most recent call last):

    sys.exit(main())

    server_stopped = self.shutdown_server(server)

    return shutdown_server(server, log=self.log)

    return future_cell[0].result()
ConnectionRefusedError: [Errno 111] Connection refused

然后我提到了这个https://discourse.jupyter.org/t/jupyter-keeps-starting-up-automatically-and-impossible-to-kill/13723

~$ ps -ef|grep jupyter
sivan     5865  5529  0 15:48 pts/5    00:00:00 grep --color=auto jupyter

为什么会发生这种情况，我现在应该怎么做？我仍然可以打开并使用 jupyter，但它真的很不稳定并且通常会崩溃。谢谢！

【解决方案1】：

我终于通过关注这篇文章解决了“没有服务器在运行，但在 jupyter 列表中有一些东西”的问题..... https://discourse.jupyter.org/t/why-does-jupyter-notebook-list-show-running-instances-when-no-jupyter-server-running/12785

因此，只需删除 jupyter 运行时文件夹中的孤立 json 文件。

jupyter --paths

cd <runtime folder>
ls

rm nbserver-<pid>.json

但是，我仍然遇到这些错误扰乱了我的工作流程..
