Windows系统OpenSSH本地连接被重置问题求助

我现在在Windows系统上配置OpenSSH遇到了麻烦，尝试过系统自带的安装方式，也手动从二进制文件安装过——把OpenSSH文件放到了C:\Program Files路径下完成安装。

OpenSSH服务器和代理看起来配置都没问题，但我尝试ssh连接localhost的时候，一直报错：

Connection reset by ::1 port 22

以下是我运行的一些调试命令及结果：

Get-Service ssh-agent

Status   Name               DisplayName
------   ----               -----------
Running  ssh-agent          OpenSSH Authentication Agent

OpenSSH-Server-In-TCP OpenSSH Server (sshd)             True

whoami

pcname\m.ceradini

ssh pcname\m.ceradini@localhost

Connection reset by ::1 port 22

我用的是默认的sshd_config，按照其他教程的建议，我尝试注释掉了配置里的Match Group Administrators，但问题还是没解决。有没有人知道这是怎么回事？该怎么修复这个连接重置的问题？

更新内容 #

下面是针对一些疑问的回复，目前ssh连接本地用户还是不行。我总结一下自己后续做的操作：

• 卸载了OpenSSH
• 删除了所有.ssh和OpenSSH相关的文件夹
• 通过Windows设置GUI重新安装了OpenSSH客户端和服务器，然后重启了电脑
• 检查了所有SSH相关命令和服务都能正常运行（Get-Command ssh、Get-Command sshd、Get-Command ssh-agent、Get-Service sshd、Get-Service ssh-agent）
• 为当前用户创建了新的密钥
• 将公钥添加到了.ssh文件夹下的authorized_keys中
• 注释了sshd_config里的Match Group administrators
• 在sshd_config中启用了PubkeyAuthentication
• 确认sshd服务处于运行状态

再次调试的结果：

Get-Service sshd

Status   Name               DisplayName
------   ----               -----------
Running  sshd               OpenSSH SSH Server

有朋友提醒说，默认配置的sshd不会处理回环设备的连接，localhost通常连不上，除非之前在对应端口开了隧道，建议我试试下面的命令：

ssh pcname

结果正常返回当前用户：

whoami

pcname\m.ceradini

然后我试了带用户名的命令，结果解析不了主机：

ssh -v pcname\m.ceradini

OpenSSH_for_Windows_8.6p1, LibreSSL 3.4.3
debug1: Authenticator provider $SSH_SK_PROVIDER did not resolve; disabling
ssh: Could not resolve hostname pcname\\m.ceradini: No such host is known.

朋友又建议如果主机找不到的话，用本地IP而不是127.0.0.1或::1，我试了：

ssh -v 192.168.83.185

调试输出如下：

朋友还说ssh默认会用当前用户，不用特意指定用户名，这样能排除错误来源，猜测我不该用pcname\m.ceradini，只用m.ceradini就行，但我不是Windows资深用户，没法验证这点。不过我已经试过所有可能的用户名组合了，结果还是一样的连接重置。
