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.
Configuration Guide
Viewing the configuration
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:
The TCP connection timeout period is 5 seconds.
The origin-pull loading timeout period is 10 seconds.
Modifying the configuration
You can click Edit on the right to modify the corresponding timeout period as needed:
The TCP connection timeout period can be set to 5–60 seconds.
The origin-pull loading timeout period can be set to 5–60 seconds.
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.
