I have create a SQL Azure database on the Azure portal, now I want to connect to it using SQL Server Management Studio. I've set my properties like this:
Server Type:Database Engine:
Server Name:[mycred].database.windows.net
Authentification: SQL Server Authentification
username: myusername
password: mypassword
But when I try to connecting with these properties I get an error:
A network-related or instance-specific error occurred while establishing a connection to SQL Server. The server was not found or was not accessible. Verify that the instance name is correct and that SQL Server is configured to allow remote connections. (provider: Named Pipes Provider, error: 40 - Could not open a connection to SQL Server) (Microsoft SQL Server, Error: 53)
Whereas I have configure firewall on my SQL Azure database. How to solve this issue?

Here is a list of test you would need to perform to troubleshoot the problem and apply solution:
