502 Bad Gateway

Categories: 0-9, SEO Glossary

A 502 Bad Gateway is an HTTP status code signaling that one server on the internet received an invalid response from another server. It’s an indication that the gateway or proxy server, which acts as an intermediary for the client, cannot get a proper response from the upstream server to fulfill the request. This error suggests a communication issue between servers, which could be temporary or require attention to resolve.
