Błąd połączenia z bazą danych Azure.

Question

Witajcie przyjaciele,

Jestem nowy na Azure. i wciąż ucząc się wszystkich wewnętrznych rzeczy. Próbuję połączyć DB i uzyskać poniżej wyjątku. Jakieś wskazówki będą bardzo mile widziane?

Zastanawiam się, czy ktokolwiek kiedykolwiek doświadczył tego lub jaki byłby tego powód? Łączenie DB:

System.Data.SqlClient.SqlException was unhandled by user code 
     HResult=-2146232060 
     Message=Cannot open server 'XXXX' requested by the login. Client with IP address 'XX.XX.XX.XX' is not allowed to access the server. To enable access, use the Windows Azure Management Portal or run sp_set_firewall_rule on the master database to create a firewall rule for this IP address or address range. It may take up to five minutes for this change to take effect. 
    Login failed for user 'User'. 
    This session has been assigned a tracing ID of 'bf7474de-2a5a-4ce2-a8fb-7d3cc57a473b'. Provide this tracing ID to customer support when you need assistance.
