使用sshfs由对等方重置连接

我使用的是保险丝/ sshfs安装架，到目前为止效果良好。现在，我不得不重新安装服务器系统，并突然收到经典read: Connection reset by peer错误。我正在使用公共密钥身份验证，并将我的密钥复制到了新安装的系统中。正常的ssh登录可以正常工作。我将日志更改为调试，但是可惜的是这并没有给我任何有用的信息：

有谁知道我在这里想念的东西吗？

更新

我尝试了手动sshfs安装，但我也得到了read: Connection reset by peer。然后，我添加了调试选项，并且也得到了Permission denied (publickey).。这很奇怪，因为公共密钥已经到位，否则可以正常工作。我还将我的用户用于ssh连接，并手动指定私钥文件。这可能是root帐户无法访问某处服务器上正确的公共密钥的问题吗？我正在执行

sudo sshfs myuser@myserver:/mnt/foo /mnt/foo -o IdentityFile=/home/myuser/.ssh/id_rsa

而相关的日志部分是

debug1: Authentications that can continue: publickey
debug1: Next authentication method: publickey
debug1: Offering RSA public key: /home/myuser/.ssh/id_rsa
debug1: Authentications that can continue: publickey
debug1: No more authentication methods to try.
Permission denied (publickey).
