The 502 bad gateway error doesn’t always appear as a simple white page with “502 Bad Gateway” written on it. You might encounter various versions of this error while browsing:
- “502 Service Temporarily Overloaded”
- “502 Proxy Error”
- “502 Server Error: The server encountered a temporary error and could not complete your request”
- “502. That’s an error”
- “502 Bad Gateway Apache”
- “502 Bad Gateway Cloudflare”
- “502 Bad Gateway Nginx”
- “Error 502”
- “Bad Gateway: The proxy server received an invalid response from an upstream server”
- “HTTP 502”
- “HTTP Error 502 – Bad Gateway”
- “Temporary Error (502)”
- A blank screen without any error message.
All these variations indicate the same 502 error. The specific message you see depends on your web browser and the web server. For instance, mentions of Cloudflare, Nginx, and Apache suggest that the issue is related to the configuration of these web servers. References to proxies indicate that a proxy server is involved and encountering an issue. The message “502 Service Temporarily Overloaded” clearly states that the server is overwhelmed.
