无法通过 mosh 连接到服务器

Question

我在Debian 上启动了服务器，安装了所有必要的设置并连接了SSH key。我连接到服务器：

ssh -i yandex_key rhost@51.250.1.155

终端输出：

Linux rhost 4.19.0-18-amd64 #1 SMP Debian 4.19.208-1 (2021-09-29) x86_64

我在服务器上运行mosh-server：

mosh-server (mosh 1.3.2) [build mosh 1.3.2]

[mosh-server detached, pid = 1739]

我回到我的本地机器并运行mosh-client：

mosh-client (mosh 1.3.2) [build mosh 1.3.2]

Usage: mosh-client [-# 'ARGS'] IP PORT
       mosh-client -c

我在终端运行命令：

MOSH_KEY=YfK...qoQ mosh-client 51.250.1.155 60001

返回：

mosh did not make a successful connection to 51.250.1.155:60001.
Please verify that UDP port 60001 is not firewalled and can reach the server.

(By default, mosh uses a UDP port between 60000 and 61000. The -p option
selects a specific UDP port number.)
[mosh is exiting.]

我尝试使用其他命令mosh [rhost@]51.250.1.155mosh rhost@51.250.1.155连接，没有结果。我联系了服务器支持，但他们说问题出在我这边。可能是什么问题呢？我需要帮助。

确保您在防火墙中打开了 UDP 端口 60000-61000。
