最近博主在学习Netty拉仓库的时候出现了这个问题
$ git clone https://github.com/fuzhengwei/itstack-demo-netty.git
Cloning into 'itstack-demo-netty'...
fatal: unable to access 'https://github.com/fuzhengwei/itstack-demo-netty.git/': Failed to connect to github.com port 443 after 21128 ms: Couldn't connect to server
解决方案:
git config --global --unset http.proxy
git config --global --unset https.proxy
