我的机架中有 2 台 UPS NUT 服务器正在运行。1 个在 TrueNAS SCALE 上运行，另一个在 Synology DS918+ 上运行。并且有一个在 ubuntu 服务器上运行的 NUT 客户端。
NUT客户不断抱怨：
Broadcast message from nut@nuc13 (somewhere) (Sat Jan 27 16:16:52 2024):
UPS [email protected] is unavailable
Broadcast message from nut@nuc13 (somewhere) (Sat Jan 27 16:16:52 2024):

有人可以帮我解决它吗？
以下是删除注释后我的 upsmon.conf 的内容：

使用telnet，似乎可以工作。以下是从 ubuntu 服务器连接到 DS918+ 的示例（这是基于 IP 的身份验证。不需要登录）：

从 ubuntu 连接到 TrueNAS 也没有问题：
