The gateway itself is usually fine. It&#8217;s the server behind it, the one actually doing the work, that dropped the ball.<br \/><br \/><\/p><p class=\"font-claude-response-body break-words whitespace-normal\" data-sourcepos=\"13:1-13:191;827-1017\">This isn&#8217;t the same as a &#8220;site not found&#8221; error.

There&#8217;s usually a reverse proxy (like Nginx) or a content delivery network (like Cloudflare) sitting in front of the actual application server.
