Question

我可以毫无问题地打开Jupyter控制台，但是当我创建一个新的笔记本时，它会一直连接到内核并与内核断开连接（消息＆＃34;连接到内核＆＃34; /＆＃34;已连接＆＃ 34;继续显示在右上角）。这就是Chrome的控制台吐出的内容（在Firefox中也是如此）：

事实是，当我在运行Jupyter服务器的同一台机器上创建一个笔记本时，一切正常（我留在家里的MacBook）。当我从另一台机器（我在公司使用的运行Windows的PC）上创建笔记本时，会出现问题。会发生什么事？

Answer 1

我刚刚将端口从8888更改为9999，问题就消失了。

使用命令

jupyter notebook --generate-config

（它表示生成的配置文件在哪里）

生成配置文件，然后找到行

c.NotebookApp.port

并更改端口。

我在nginx代理后面使用jupyter。我遇到了和你一样的问题。深入研究后，我发现问题存在于我的nginx conf。

中

将以下行添加到我的nginx conf后，它可以正常工作！

proxy_http_version 1.1;

这是完整的nginx conf：

upstream my-notebook-workhorse {
  server 127.0.0.1:8888 fail_timeout=0;
}

map $http_upgrade $connection_upgrade {
    default upgrade;
    '' close;
}

# let my-notebook deal with the redirection
server {
  listen                    80;
  server_name               my-notebook.wh;
  server_tokens             off;
  root                      /dev/null;

  # Increase this if you want to upload larger attachments
  client_max_body_size      20m;

  # individual nginx logs for this vhost
  access_log                /var/log/nginx/my-notebook_access.log;
  error_log                 /var/log/nginx/my-notebook_error.log;

  location / {
    proxy_pass http://my-notebook-workhorse;
    proxy_set_header X-Real-IP $remote_addr;
    proxy_set_header Host $host;
    proxy_set_header X-Forwarded_For $proxy_add_x_forwarded_for;
    proxy_set_header X-NginX-Proxy true;
    auth_basic "Restricted Content";

    # WebSocket support
    proxy_http_version 1.1;
    proxy_set_header Upgrade $http_upgrade;
    proxy_set_header Connection $connection_upgrade;
    proxy_set_header Origin "";
    proxy_read_timeout 86400;
  }
}

我不知道为什么会发生这种情况，因为没有proxy_http_version 1.1;的旧版本在我遇到问题之前的最后几个月运作良好。
