Ensure that 'Secure transfer required' is set to 'Enabled' for Storage Accounts

Azure Storage Account

An Azure storage account provides a unique namespace to store and access your Azure Storage data objects. All objects in a storage account are billed together as a group. By default, the data in your account is available only to you, the account owner.
