Error 502: Bad Gateway is one of the most intrusive HTTP errors. Like any other online error, there are specific causes for the Error 502 message to be prompted. The error message may appear when one server on the internet received an invalid response from another server. The server was performing as a gateway or proxy and received an invalid response from the upstream server.
How to Identify a 502 Bad Gateway Error?
The 502 Bad Gateway error displays inside the internet browser window, just like web pages do but spotting it is not as easy as you think. This code doesn’t necessarily present itself in the same way, each time that it’s encountered. Don’t expect the number “502” to be present in the error message in every case of Error 502. For example, Twitter’s famous “fail whale” error that says “Twitter is over capacity” is actually a 502 Bad Gateway error. In the same way, websites could have customized their 502 error message. Let’s have a look at some of those examples:
- 502 Bad Gateway.
- Error 502.
- HTTP 502.
- HTTP Error 502 – Bad Gateway.
- 502 Proxy Error.
- 502. That’s an error.
- Temporary Error (502).
- 502 Service Temporarily Overloaded.
- 502 Server Error: The server encountered a temporary error and could not complete your request at the moment.
- Bad Gateway: The proxy server received an invalid response from an upstream server.
What Causes of 502 Bad Gateway Error?
502 Bad Gateway error is a server-side error. You can “technically” do nothing to fix it as the issue is with the server who is responsible for hosting the site.
The cause is simple, two online servers are having trouble communicating. This is the main cause but this is not the end of the story, the 502 error is the server’s problem but sometimes, this error message can be displayed in case of another problem due to a fault in a web browser.
In some outlying circumstances, your browser “thinks” that there is an issue between online servers when there isn’t one. This is all thanks to an issue with your browser, a problem with your home networking equipment, or some other in-your-control reason.
