Jupyter 无法连接到 Python

问题描述

1	kernel connecting

及无法连接到后端的 Python, Shell 也无法打开

架构

笔者采用 jupyter docker + nginx 反向代理这个模式

打开日志发现

1	[W 2022-02-22 15:14:10.078 ServerApp] 400 GET /terminals/websocket/1 (172.18.0.1) 0.67ms referer=None

解决方法

更改 nginx 反向代理配置, 可能是没有识别websocket请求所致, 具体原因尚不清楚, 但以下这个配置在笔者这里可用
