Last Updated: Dec 29, 2020

Problem description

After you use a CDN domain name, the error message 504 Gateway Time-out is returned.

Cause

The origin server is abnormal. When CDN retrieves data from the origin server, the error occurs if the origin server does not respond within 30 seconds.

Solution

  1. Check whether the CPU and bandwidth resources of the origin site server are abnormal. If any abnormality occurs, refer to network traffic load query and case analysis and query CPU load and case analysis for troubleshooting.
  2. Modify the host file on your local computer to redirect the domain name to the IP address of the source server. For more information, see procedure to bind a domain name.
    • Access the domain name and check whether the request Time parameter in the Network exceeds 30 seconds in the review element of the browser. Time. If the duration of the response is more than 30 seconds, we recommend that you check the service of the origin server to ensure that the response time is within a short period.
