VPS host SSH and SFTP can log in but the website cannot be opened. Solution

There are several websites in a certain VPS host. I used llsmp to install the environment with one click. When I was about to open the website at night, I saw that the website could not be opened. Then I logged in through SSH to check the problem, because the snail did not want to worry about the logs. Too many, so no log file is created. Originally, if such a problem occurred, it could be analyzed directly from the log. I personally feel that the VPS host is down, and then my machine is not activated after restarting. I've encountered this once before.

My customary method is to restart Litespeed:

/etc/init.d/lsws restart

It should be solvable after restarting, at least my problem can be solved. If friends encounter such a problem, this is how to solve it. It seems that I still have to create a log file tomorrow.
