当我使用docker run命令使用Docker图像时，我无法在web浏览器中打开Jupyter Notebooks。我得到以下错误:
This site can’t be reached. The webpage at http://127.0.0.1:8888/?token=8543b16468608a7d26b8183256a97ebc3df41bf8838a3729 might be temporarily down or it may have moved permanently to a new web address. ERR_SOCKET_NOT_CONNECTED
docker-compose命令，一切都可以正常工作。我还尝试构建图像，然后运行图像，但这也不起作用。我从Dockerfile构建:
docker build -t notebook .
，然后做
docker run --rm -p 8888:8888 -v $(pwd):/home/jovyan/work notebook
当我尝试使用Jupyter Notebook时，似乎只有使用docker-compose对我有效。有人知道为什么吗?
OS: Ubuntu 20.04 LTS

Docker运行命令和输出(不工作)
docker run --rm -p 8888:8888 -v $(pwd):/home/jovyan/work jupyter/minimal-notebook:notebook-6.4.3
终端

Docker撰写命令及输出(works)
我有一个dock -compose。Yml文件

services:
jupyter: # you can change this "jupyter" service to whatever you want.
build:
context: ./docker-folder # this is where the build directory is aka. Dockerfile.
image: compose-test
volumes:

ports:

docker-folder
文件夹中包含以下内容的DockerfileFROM jupyter/minimal-notebook:notebook-6.4.3
docker-compose build && docker-compose up
jupyter笔记本在web浏览器中打开没有任何问题。终端中的输出如下

结束docker-compose down -v
回答:显然，这个问题是由我的VPN引起的(我使用Express VPN，但不确定是否也适用于其他VPN)。如果我打开电脑并执行docker run ...，一切都可以正常工作。如果我打开VPN，就会出现错误。即使我关闭VPN，错误也会继续发生。但是，如果我重新启动计算机并再次执行docker run命令，一切都完全正常。
我不知道为什么，但我从来没有得到错误，当我使用我的docker-compose文件，它总是工作。
