502 bad gateway

A 502 Bad Gateway Error generally indicates that there are issues with the website’s server connectivity (not responding).

What is the 502 bad gateway?

The 502 Bad Gateway error signifies that the server received an incorrect response from an inbound server.

Every time you visit a website, your browser requests the web server. The web server accepts the request, processes it, and returns the requested resources with an HTTP header and an HTTP status code. An HTTP status code is rarely encountered unless something goes wrong. It’s essentially the server’s approach of telling you something has gone wrong, along with the code for diagnosing the problem.

What causes 502 bad gateway error

What causes the 502 Bad Gateway error?

A 502 error indicates that something is amiss with a website’s server connectivity. Because it is a generic error, it does not provide information about the specific issue with the website.

The typical causes of the 502 Bad Gateway include:

  • Server overload: The server ran out of resources and crashed, resulting in HTTP error 502. Possible causes include an unexpected rise in traffic or a lack of memory.
  • Browser issues: your browser version is outdated, or your browser cache contains corrupted files.
  • Firewall block: Your firewall might identify false threats and prohibit internet providers or IP addresses.

How do I fix Bad Gateway 502?

There are several common and efficient techniques for identifying and resolving the majority of 502 Bad Gateway Errors.

Sometimes, server connectivity issues are fixed quickly. Before delving into the source of the problem, take steps to establish that it is a severe error rather than a blip. Wait for a minute or two, then reload the page. It could have been a brief connectivity issue if the page loads without error. If the page still returns an error, remove your browser cache and try refreshing it again.

Another thing to verify is your server’s connectivity. Most websites are hosted on many servers or through third-party hosting services. If your server is unavailable for maintenance or any other reason, visitors to your website may receive a 502 Bad Gateway Error page.

Also, look at your firewall configurations. Your firewall protects your website from malicious actors and distributed denial-of-service (DDoS) attacks, which could be infected with malware.

A flawed firewall configuration can cause your firewall to treat requests from a network as an attack on your server and reject them, resulting in a 502 Bad Gateway error. Check your firewall configuration to identify and resolve the problem.

Does 502 Bad Gateway mean blocked?

A 502 Bad Gateway error is not a block – it happens when communication breakdown between two servers is broken.

Is 502 Bad Gateway a hack?

The 502 Bad Gateway error is not a hack. This error can occur when you visit a website that receives an invalid response from its host server or encounters other issues, such as server overloads, network problems, or configuration issues. The 502 bad gateway error does not indicate that your device or internet connection is amiss.
