我最近刚买了一个全新的 OVH VPS，除了 Apache 之外没有安装任何东西。当我尝试通过 FileZilla 连接到 VPS 时，我收到以下信息：
Status: Connecting to xxx.xxx.xxx.x:21...
Status: Connection attempt failed with "ECONNREFUSED - Connection refused by server".
Error: Could not connect to server
以下是我试图联系的详细信息：
Hostname: xxx.xxx.xxx.x (IP of the VPS)
Username: root
Password: ******** (root Password)
Port: 21
