Error Description
What should I do if a 404 status code is returned by a CDN domain name?
Cause
1. The origin server is exceptional.
2. The configuration of the origin server information and host header in the console are changed.
Solution
1. Check whether your origin server works properly.
2. Check whether configuration of the origin server information and host header in the console are correct.
Troubleshooting Procedure
1. Check whether your origin server is exceptional.
If it is so, fix the origin server.
If it is not, go to Step 2.
2. Check the configuration of the origin server information and host header in the console.
Log in to the CDN console, select Domain Management, find the corresponding domain name, select Basic Configuration > Origin Server Information, and check whether the settings of Origin address and Host header are correct.
Origin type:
Customer origin server | If you select customer origin server, you should provide an IP address or domain name of the business server that can be normally accessed. |
COS origin server | If you select a bucket in COS as the origin server, select Default Domain or Static Website based on your bucket configuration. If your bucket is private, authorize CDN and enable origin-pull authentication to turn on private bucket access. |
Third-Party object storage | If you select a third-party object storage service, enter the valid bucket access address as the origin server. Currently, AWS S3 and Alibaba Cloud OSS are supported. If the bucket is private, enter a valid key and enable origin-pull authentication to turn on private bucket access. |
Host header:
It refers to the domain name accessed on the origin server by a CDN node during origin-pull. It defaults to the acceleration domain name. If a wildcard domain name is connected, it will be the actual access subdomain name by default and can be customized. (Note: it cannot be modified if the origin server type is COS or a third-party object storage service).
