Revision 1096231 of 502 Bad Gateway

<div>{{HTTPSidebar}}</div>

<p>The HTTP <code><strong>502</strong></code><strong><code> Bad Gateway</code></strong> server error response code indicates that the server, while acting as a gateway or proxy, received an invalid response from the upstream server.</p>

<p>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>
