我对 DigitalOcean droplet 还比较陌生，但在遇到问题之前，我已经使用 Ubuntu 18.04 droplet 运行 Nextcloud 实例几个星期了。我不能 100% 确定问题出在哪里，而且我的故障排除也没有什么进展。
我错误配置了一台 Nextcloud 客户端计算机，它推送的文件数量超出了空间。我的 Droplet 使用率为 100%，客户端计算机无法连接到它。它可用于 SSH。
当我通过 SSH 进入机器或使用 DO 控制台时，系统会立即要求我更改 root 密码。更改成功后，它会立即关闭连接。再次连接时，它会再次要求更改密码 - 我陷入了循环。
SSH -vv 输出：
Changing password for root.
