aaP_myanmar Hello!
404: the page visited does not exist or the file path cannot be found
Here, you need to distinguish whether the accessed page is a static page (HTML) or a dynamic page (PHP, etc.)
If it is a static page access 404, it may be a file path error or a site directory binding error,
At this time, check whether the file path is correct and whether the site domain name binding directory is correct
If it is a dynamic page 404, it may be a pseudo static setting error. You need to check whether the pseudo static setting is correct
At the same time, if PHP is not started normally or the concurrency is too high, it may also lead to site 404
At this time, you need to check the running status of PHP to see if it is running normally
