我在连接到 AWS 上的 Jupyter 笔记本实例时遇到了问题。这有点超出我的驾驶室，所以任何帮助将不胜感激！

您找到解决方案了吗？
也有同样的问题，希望有人找到解决方法。找到了这个 github 问题，但似乎没有为我解决任何问题github.com/jupyter/notebook/issues/507

标签： python-3.x amazon-web-services anaconda jupyter-notebook jupyter

【解决方案1】：

所以我遇到了这个问题，这是由于您的 jupyter 配置文件中引用的证书文件存在权限问题。在 jupyter_notebook_config.py 中，我引用了 mycert.pem。我将 mycert.pem 的所有权更改为我的标准用户帐户。

sudo chown user:user ~/certs/mycert.pem

这解决了问题。

【讨论】：

在一个 ec2 ubuntu 实例上，我将命令更改为 sudo chown $USER:$USER ~/certs/mycert.pem，它也能正常工作。感谢您的帮助
我知道点赞就够了，但我真的必须说...谢谢！ @GeochemB

【解决方案2】：

检查以下几项以确保您在 AWS EC2 机器上使用 jupyter notebook 时处理 permission error：-

1：确保不要使用private ip，而是使用public ip，

2: 处理证书权限错误后出错

sudo chown $USER:$USER /home/ubuntu/certs/mycert.pem

3：处理SSL error，确保在ip:<port number>之前使用https://

4：请务必检查security group 的inbound 规则，以确保您尝试正确访问ports。
