They are almost everywhere. Even on the internet. One of the very few places that are expected to be perfect, due to how frequently it is used in our lives. But at the end of the day, what matters is that we realize our mistake, and work towards making amends.

Now on the internet, there are hundreds of mistakes that occur. The technical term for these mistakes is- ‘Web Error’. Each error that occurs, has a code that helps in identifying the exact problem, which is called ‘HTTP STATUS CODE’.

It is important to remember that these errors may occur not just on the user’s side but also on behalf of the company that runs the website or simply just on the website’s behalf, in case it is independent in nature and is run by a specific individual or a group of individuals that run the website. For example- error 404, error 500, error 402, error 502.

WHAT IS ERROR 502?

Error 502 also known as 502 Bad Gateway is an HTTP status code that means that the requested web address is invalid. This doesn’t necessarily mean that there is an issue with the user’s connection. There is also a possibility of having an issue on the website’s behalf.

Error 502 is not affected by the type of browser or even the operating system in use. It is simply an error that occurs on the internet. When error 502 occurs, it may appear in many names such as-

  • 502 Bad Gateway

HOW IS IT CAUSED?

Now that we know what Error 502 exactly is, the next step is to understand how it is really caused. This error mostly arises due to the following reasons-

  • Failed server- In case the web address crashes or the server is unable to complete a task, the error arises. For example, when a particular website is blocked in the region where the user is located.
  • Overloaded Webserver- When there is an excess of traffic on a particular website this error is caused, because the server reaches its limit and cannot take any further requests, consequently leading to Error 502 also known as 502 Bad Gateway.
  • Failed PHP( Hypertext Pre-processor, previously known as Personal Home Page) Programming-PHP is a server-side scripting language for web development. According to this in certain cases, an error may occur as there is an issue in the coding of the website resulting in error 502.
  • Error in communication- Sometimes, a faulty firewall, which is basically a network security system the manages the network traffic based on the security rule, may also lead to disruption of the communication process between the server and the user, leading to failure in forwarding the request.
  • Error in the browser- trouble in the browser extension of a website is also considered to be a common cause of 502 Bad Gateway.
