Bug Description

The following error message occurs when I try to view the blob containers in my storage account.

This request is not authorized to perform this operation.

This storage account's 'Firewalls & virtual networks' settings may be blocking access to storage services. Try adding your client IP address to the firewall exceptions, or by allowing access from 'all networks' instead of 'selected networks'.
