Не удалось выделить необходимые адресные пространства

При развертывании новой веб-роли в Windows Azure я получаю сообщение об ошибке: Невозможно выделить необходимые адресные пространства для развертывания в новой или предопределенной подсети, которая содержится в указанной виртуальной сети. Я выполнил поиск. для решения, но не нашел его. У кого-нибудь есть идея?

Мой файл cscfg выглядит так:

<?xml version="1.0" encoding="utf-8"?>
<ServiceConfiguration serviceName="Application.Cloud" xmlns="http://schemas.microsoft.com/ServiceHosting/2008/10/ServiceConfiguration" osFamily="3" osVersion="*" schemaVersion="2013-03.2.0">

      <InstanceAddress roleName="WebApplication">

        </Subnets>

    </AddressAssignments>
  </NetworkConfiguration>
</ServiceConfiguration>

В том же облачном проекте у меня есть еще один экземпляр, который отлично развертывается.
