When Tencent Cloud CDN forwards a request to the origin server, the default timeout period for TCP connection is 5 seconds, and the default timeout period for data loading during origin-pull is 10 seconds. If the origin-pull duration exceeds the aforementioned time limits, failures will often occur.
You can adjust the timeout periods for origin-pull TCP connection and data loading according to your origin server data processing conditions and network environment so as to ensure normal origin-pull.
Log in to the CDN Console, select Domain Management on the left sidebar, and click the domain name to enter its configuration page. You will find the origin-pull timeout configuration on the Origin Configuration tab. By default:
You can click Edit on the right to modify the corresponding timeout period as needed:
If your acceleration domain name is configured for global acceleration, the configured origin-pull timeout period will take effect globally. This configuration does not distinguish between requests from Mainland China and from outside Mainland China.
