It’s essential to have complete knowledge of the illness before prescribing the necessary treatment. You need to know what error has occurred, and what caused it before you can effectively fix it. In this article, I’ll explain What WordPress 502 Bad Gateway Error is and how to fix 502 bad gateway error in WordPress website.
When your website has the WordPress 502 Bad Gateway error, it’s like solving a mystery. You don’t know what specifically happened or why you think everything is wrong, so you need to fix it.
The 502 Bad Gateway Error
The 502 Bad Gateway Error occurs when a browser cannot load data from a server. To understand what this looks like, you should know how a browser loads data from the server. When user request access to a website, the server sends a request to fetch the data required for displaying content in their browser.
If the server is able to respond to the requests, it will get the requested content. If not, a 502 Bad Gateway Error screen will come up instead.
The WordPress CMS utilizes the power of multiple servers at once to handle the different demands on your website. For Example:
- Database server to manage Database.
- PHP and other app-related content will be run on an Application server.
- The Proxy server is responsible for Apache and NGINX.
- Website files are managed using the web server.
A reversed proxy server provides the browser with a way to fetch data from other servers. It receives requests, like database lookups, web requests, and application requests (for example).
If any of these servers respond with an invalid response, the reverse proxy server will return the response to the browser and display a 502 Bad Gateway Error.
