  • 502 Bad Gateway - Origin Connection Expired
    Error 502
    CLIENT_IP: "216.73.217.121"
    NODE_ID: "38.182.168.243"

    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.
