How to configure loki.yml to use Azure's blob storage

On my local server , I want Loki to use Azue’s blob storage. The configuration of loki.yml is as follows:

storage_config:
  tsdb_shipper:
  active_index_directory: /www/loki-data/index
  cache_location: /www/loki-data/index_cache
  cache_ttl: 24h
  azure:
    account_name: test
    account_key: "c3A9eGFkdCZzdD0yMDI0LTA3LTA1VDA2OjA5OjAzWiZzZT0yMDI0LTEyLTMxVDE2OjAwOjAwWiZzcHI9aHR0cHMmc3Y9MjAyMi0xMS0wMiZzcj1jJnNpZz1BbHNnSGZhTG43RDhlNSUyRjB5JTJGbG5IN1UlMkZ4UUFoTkVxUmJwYWxVWEpERXd3JTNECg==" # This is the value after base64 encoding
    container_name: loki-test
    use_managed_identity: false
    request_timeout: 0

schema_config:
  configs:
    - from: 2022-06-25
      store: tsdb
      object_store: azure
      schema: v13
      index:
        prefix: baoyu_
        period: 24h

But after startup, an error occurred later. It seems that authentication failed when flashing the data block to the blob:

My account name and account key can be uploaded to blob storage on the same server using the az command (azured command-line client), indicating that account name and account key are correct. for example :
az storage blob upload --container-name loki-test --account-name test --account-key ‘xxxxxxx’ --file test.txt
My Loki version: 2.9.8

How can I configure loki.yml to use Azure’s blob storage?
