Understanding the 502 gateway error
A 502 response means that an intermediary server received an invalid response from the upstream host while attempting to complete your request. In this case, your browser and the Cloudflare network are reachable, but the origin host is not returning a usable response. The problem may be temporary, or it may indicate an issue with the application, web server, network connection, or a recent configuration change.
A gateway error does not usually indicate a problem with your device. It can occur when the origin server is overloaded, restarting, unavailable, incorrectly configured, or taking longer than the gateway allows. Repeating the request after a short interval is often enough when the condition is caused by a brief service interruption.

Recommended troubleshooting steps
- Refresh the page after waiting a few minutes. A full reload can also be useful if the first response was cached by the browser.
- Check whether other pages on the same website are available. A single route may be failing while the rest of the service remains operational.
- Try a different network or browser if the error persists. This helps determine whether the request path is specific to your current connection.
- Avoid repeatedly submitting forms or payments while the gateway is unavailable. Confirm the result of an earlier request before trying it again.
- Contact the website administrator and include the time, requested URL, error code, and Cloudflare Ray ID shown on this page.
Information for site administrators
Administrators should first confirm that the origin server is running and accepting connections on the expected port. Review application and web-server logs for the time of the incident, then check recent deployments, DNS changes, firewall rules, TLS settings, and upstream dependency failures. Resource exhaustion, process crashes, connection pool limits, and invalid proxy settings are common causes of a 502 response.
| Area to check | Useful verification |
|---|---|
| Origin availability | Confirm the service is running and responds directly from the server. |
| Proxy configuration | Verify the upstream address, port, protocol, and host headers. |
| Capacity | Inspect CPU, memory, file descriptors, worker limits, and connection queues. |
| Security controls | Check firewall, allow-list, rate-limit, and certificate changes that could block the edge network. |
Frequently asked questions
Is a 502 error caused by my browser?
Usually not. The browser successfully reached the gateway, while the gateway could not obtain a valid response from the origin host.
Will refreshing the page fix the problem?
It may, especially when the origin service is restarting or experiencing a short-lived overload. Wait briefly between attempts and avoid duplicating transactions.
What should I send to support?
Provide the full URL, UTC timestamp, error code, Cloudflare Ray ID, and any relevant details about what you were doing when the response appeared.
Conclusion
The gateway and browser connection are available, but the requested origin response could not be completed. Visitors should retry later, while administrators should use the timestamp and Ray ID to correlate gateway requests with origin logs and restore normal service.
