无缘无故的连接不上了 问客服客服说：
Hello,
I see that your server is pinging, but is not responding to either SSH or HTTP. This can either be caused by the services not running, or a firewall blocking access. It looks like you will need to login via the web console to further investigate.
You can see which services are listening with "netstat -nltp" and if you see SSH and HTTP, the issue is likely with your firewall.
If using the default Ubuntu firewall, you can check it's status with "ufw status verbose", and enable ports with "ufw allow 80" for HTTP for example.
Let us know if you have any further questions.
