Spring cloud 配置中心 https://github.com/xxxx: cannot open git-upload-pack

1. 问题
   检查过配置都正确
   启动后日志报：org.eclipse.jgit.api.errors.TransportException: https://github.com/xxxxx: cannot open git-upload-pack
   
   尝试本地git拉取，git报：OpenSSL SSL_connect: Connection was reset in connection to github.com:443
   因此git配置

   git config --global http.sslVerify false

解决git问题，然而cannot open git-upload-pack问题依旧

2. 解决
   改用ssh方式
   开始用 ssh-keygen -t rsa -C “邮箱” 生成ssh,然而重启配置中心后会报Auth fail
   因而改用ssh-keygen -m PEM -t rsa -b 4096 -C "邮箱"生成ssh,重启配置中心后问题解决
