本地生成id_rsa.pub内容和authorized_keys内容匹配。

但现在push无法工作， http和ssh方式都不行，希望有经验的高手能帮我看看、谢谢

push错误信息：
$ git push -u origin master
Permission denied (publickey,password).
fatal: Could not read from remote repository.

Please make sure you have the correct access rights
and the repository exists.

网上的各种修改都试过了无解。
