Site going Up and Down

  • Hello, We have a wordpress site hosted on Dedicated server on AWS, and is using Nginx server and Php-Fpm service. Site goes down multiple times and show error – Request failed with status code 504. I have checked DB, code as well as CMS for any issues. Couldn’t find any problem.

    DB is in AWS RDS, but on same server there is another PHP website which uses RDS with different DB. That site never faces any issue. So probably no issue from server end. But wordpress is having issues.

    Please guide me to solve this issue

    504 means your web server asked another server (database, cdn, etc) for information it needed and didn’t get it back in time. I’d look in your nginx error log files for the actual error as it’s reported, I suspect you’ll find out which thing isn’t being speedy enough.

    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.
