How to fix website not loading issue on VPS server (Nginx + WordPress)

admin

Hi,

My WordPress website is hosted on a VPS server using Nginx, but it is not loading properly. Sometimes it shows a 502 Bad Gateway error, and sometimes the page keeps loading without showing anything.

Server Details:

  • VPS (Ubuntu 22.04)
  • Nginx server
  • WordPress installed

What I tried:

  • Restarted Nginx and MySQL
  • Checked server status
  • Cleared cache

Still the issue is not fixed.

Can anyone help me:

  1. What is causing this issue?
  2. How to check Nginx error logs?
  3. How to fix 502 error on VPS?

Thanks
