This guide details the "502 Bad Gateway" errors that you may encounter when visiting a website.

Introduction

• The 502 Bad Gateway error occurs when the server acting as a gateway between the browser and the origin web server receives an invalid response.
• This error can be caused by an overloaded web server, communication issues between a CDN and the web hosting server, or a misconfigured proxy server.
• Sometimes, the error may be caused by an incorrect entry in the DNS server.

Troubleshooting steps

To resolve the 502 Bad Gateway error, it is often necessary to proceed by elimination:

• Check if it is not a temporary server overload: simply reload the page after a few minutes and the error should disappear.
• Clear your browser's cache.
• Try using a different browser.
