remote: Public key authentication failed. fatal: Could not read from remote repository.

回答:问题中提到了两个不同的错误，一个是"remote: Authentication failed"，另一个是"remote: Public key authentication failed. fatal: Could not read from remote repository."。根据引用和的内容，这些错误提示是在使用Git向Coding平台进行操作时出现的。首先，"remote: Authentication failed"错误提示表示认证失败，需要确认输入的账号密码是否正确，可以尝试重新输入账号密码来解决这个问题。其次，"remote: Public key authentication failed"错误提示表示公钥认证失败。根据引用的内容，可以尝试使用公钥来进行认证。首先需要登录码云账号，然后添加相应的公钥，最后再次运行push命令。这样应该可以解决这个问题。
