Mac主机SSH连接UTM Ubuntu虚拟机无响应问题排查求助

大家好，我目前遇到了一个SSH连接的问题，想请各位帮忙分析下：

我在Mac主机上用UTM运行Ubuntu 22.04.3虚拟机，已经在UTM里配置了端口转发——将虚拟机的22端口（SSH默认端口）映射到主机的2222端口。

但当我在主机终端执行命令 ssh benwal@localhost -p 2222 时，没有任何错误提示，进程就一直挂着：既不要求我输入密码，也不会自行终止，完全没有响应。

我试着用 verbose 模式运行了命令 ssh -vvvvv benwal@localhost -p 2222，得到的输出如下：

OpenSSH_8.6p1, LibreSSL 3.3.6

从输出看连接已经建立了，但之后就没有后续的认证步骤，完全卡在这儿。有没有大佬能帮我看看问题出在哪儿？
