无法在本地网络连接Docker容器问题求助

作为Docker及网络技术新手，在Ubuntu Server环境下尝试运行QuakeJS容器时无法连接，遂先通过nginxdemos/hello容器排查问题，执行命令：

docker run -d -p 8080:80 nginxdemos/hello

排查过程 #

• 在Chrome和Firefox浏览器中访问172.17.0.0:8080等地址均超时
• 安装基础Apache服务器可正常访问，初步判断问题出在Docker

后续更新与解决 #

• 执行docker ps确认容器正常运行：

CONTAINER ID   IMAGE              COMMAND                  CREATED             STATUS             PORTS                                   NAMES
a7bbfee83954   nginxdemos/hello   "/docker-entrypoint.…"   About an hour ago   Up About an hour   0.0.0.0:8080->80/tcp, :::8080->80/tcp   relaxed_morse

• 本地执行curl localhost:8080可正常获取Nginx页面
• 先后尝试禁用ufw、使用ufw-docker工具，均未解决问题，最终重启Docker服务后故障修复
