I am stuck at this problem for two days.

I have added 4 blob storage origins in a single origin group at azure front door. I am doing hit and trial on blob sas tokens.

I have not updated any settings like weights and prioity, health probes are enabled.
Please tell me what i am doing wrong.

async uploadFile(file: File, link: string, tokens: { token: string, accountName: string }[], container: string) {
        const fileName = `${file.name}-${Date.now()}`;
        let response = null
        for (let token of tokens) {
            try {
                console.log(token)
                const blobServiceClient = new BlobServiceClient(`${link}?${token.token}`);
                const containerClient = blobServiceClient.getContainerClient(container)
                const blockBlobClient = containerClient.getBlockBlobClient(fileName);
                const responseBlob = await this.upload(file, blockBlobClient)
                if (responseBlob.errorCode) {
                    continue;
                }
                response = {responseBlob,accountName:token.accountName};
                                return response

            } catch
            (e) {
                console.log(e);
                continue;
            }
        }
        return {response,fileName}
    }

Expectation:
Upload file to the best and nearest origin to the end user.
Result:
Front door ALWAYS uploads file to the LATEST added storage account or the last one.
