Cloudfare with Aliyun OSS meet error, how to resolve it?

[user8363]

Hi,I create a bucket on Aliyun OSS, its public url is xxxx.oss-us-east-1.aliyuncs.com, so I set a cname on cloudflare. But when I visit new site with custom domain via browser, instead of OSS bucket file content, I get an error message -> “The bucket you are attempting to access must be addressed using the specified endpoint. Please send all future requests to this endpoint”. How to handle it, Cloudflare + Aliyun OSS?
thanks

Usually we can’t directly CNAME to bucket storage endpoint.

You may need to try this:

Securely access and upload assets with Cloudflare R2 · Cloudflare Workers docs

Basically what it does is, rewrite the host header to your Aliyun hostname.

thanks a lot, it works!
and by the way, this can enjoy free flow fee? you know Aliyun also join Cloudflare’s Bandwidth Alliance.

I’m not sure about this. See whether someone from Cloudflare can explain about it?

later find a resolution without worker, aliyun has a strict, need to bundle custom domain with Aliyun OSS bucket on their dashboard. After do that, the error disappeared.

thanks
