<p>HyperText Transfer Protocol (HTTP) <code><strong>502 Bad Gateway</strong></code> 에러 응답코드는, 서버가 게이트웨이나 프록시 서버 역할을 하면서 업스트림 서버로부터 유효하지 않은 응답을 받았다는 것을 가르킨다.</p>
<div class="note">
<p><strong>Note: </strong>A {{interwiki("wikipedia", "Gateway_(telecommunications)", "Gateway")}} might refer to different things in networking and a 502 error is usually not something you can fix, but requires a fix by the web server or the proxies you are trying to get access through.</p>
