Ensure that 'Secure transfer required' is set to 'Enabled'

The secure transfer option enhances the security of your storage account by only allowing requests to the storage account by a secure connection. Azure storage does not support HTTPS for custom domain names, so this option is not applied when using a custom domain name.

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.
