git remote remove origin后在使用git remote add origin命令添加后提交代码报错

git remote remove origin后在使用git remote add origin命令添加后提交代码报错：fatal: The current branch master has no upstream branch.
To push the current branch and set the remote as upstream, use

git push --set-upstream origin master，

git branch -a查看分支：只有master分支，

使用 git push -u origin master命令 报：fatal: unable to access 'http://x@x/r/CDM/HeartLove.git/': Failed to connect to 127.0.0.1 port 10080: Connection refused

建议删除.git文件重新操作
