502 Bad Gateway - Origin Connection Expired Error 502 CLIENT_IP: "60.205.58.245" NODE_ID: "154.194.65.100" Origin Request Timeout / Bad Gateway What happened? The CDN edge node successfully received the request, but the origin server failed to respond within the configured time limit. The server, while acting as a gateway or proxy, did not receive a timely response from the upstream server. How to solve? As a visitor: The origin server may be slow or experiencing network congestion. Please try again later. Administrator Troubleshooting Tips: 1. Check the origin server load and verify whether CPU or database performance is a bottleneck. 2. Check firewall rules on the origin server to ensure CDN nodes are not blocking long-lived connections. 3. Verify the network quality between the CDN and origin, or consider increasing the timeout settings on the CDN side.
