Hi Topher, Thanks for the reply.
Below is the common error I saw in nginx error log.
2022/01/07 08:04:35 [error] 1221#1221: *528105 open() "/var/www/html/wordpress/wp-content/uploads/2021/09/[email protected]" failed (2: No such file or directory), client: 10.0.0.179, server: xxxxxx, request: "HEAD /wp-content/uploads/2021/09/[email protected] HTTP/1.1", host: "xxxxxxx", referrer: "xxxxxxxx"

I am not sure why this file or folder is missing. There are lots of failed requests for this URL when the site went down.
