先替换：git config --global url."https://hub.fastgit.xyz/".insteadOf https://github.com/
然后替换回去：git config --global url."https://github.com/".insteadOf https://hub.fastgit.xyz/
报错：fatal: unable to access 'https://hub.fastgit.xyz/system-pclub/GFuzz.git/': Failed to connect to hub.fastgit.xyz port 443 after 21156 ms: Couldn't connect to server
求解

后面那个不是替换回去，而是创建了两条不同的配置。你应该把前面那一条unset掉
