我在本地计算机上为 AWS 实例生成了一个新的 SSH 密钥（使用密码）。然后通过 SSH 进入该实例，并将我的公钥上传到authorized_keys.
我以前可以连接和移动文件（获取和放置）成功通过终端 (STFP)。但在 FileZilla 中，我能够连接并查看所有文件，并从本地计算机移动到服务器，但不是从服务器到我的本地机器.FileZilla 一直显示：
Disconnected: No supported authentication methods available (server sent: publickey)
造成这种情况的原因是什么？

FileZilla 版本：3.43.0（最新）操作系统：MacOS Mojave 10.14.5
正如您所看到的，连接成功Directory listing of "/var/www/html" successful，然后我移动了一个文件（从服务器到本地），但仍然收到错误。
更新 2： 现在我明白问题所在了。FileZilla 最初使用 svParis.ppk 进行连接，然后当我尝试移动文件时，它使用 ParisInstance.ppk（我更改的旧密钥）。
为什么会发生这种情况？是因为我手动将公钥添加到我的实例（而不是从 AWS 控制台添加）吗？
答案1
解决~/.config/fiezilla在 FileZilla 关闭时删除该文件夹。
为什么：
扫描配置文件夹，显示我的旧密钥ParisInstance.ppk仍然写入其中一个文件 ( filezilla.xml)，尽管sitemanager.xml密钥正确。但是，删除文件夹、启动 FileZilla 并再次添加服务器连接信息后，它就正常工作了。
