Failed to Import Data - SQL Azure direct connection

I am now trying from Power BI Desktop to connect to the same SQL Azure database and get the following:

 

Unble to Connect

Details: "Microsoft SQL: Connection Timeout Expired.  The timeout period elapsed while attempting to consume the pre-login handshake acknowledgement.  This could be because the pre-login handshake failed or the server was unable to respond back in time.  The duration spent while attempting to connect to this server was - [Pre-Login] initialization=58; handshake=14931; "

 

I am able to connect fine with SSMS to the SQL Azure database from the same machine. Any ideas?

 

thanks,

Mark

    mwiggins by "verified the firewall rule is set to on" can I assume that the IP you set as a rule is not your internal network IP, but is the IP that your internet connection has, and that the user you are trying to connect to the database has permissions.

    My initial impression is that this is a config issue and not a Power BI issue.

      By "verified the firewall rule is set to on" I meant the "Allow access to Azure services" (see attached) to connect from the Power BI portal. I did also add my NAT'd IP address to the firewall rule, to test the connection from SSMS and Power BI Desktop running on my local machine. SSMS is able to connect but PowerBI Desktop is not, see previous message.

       

      thanks,

        I read you message. Just because you can access from SSMS doesn't mean that Power BI Desktop or Service interacts with the database in the same way.

        If you head here https://support.microsoft.com/en-us/kb/2980233

        You can start the guided walkthrough to troubleshoot connection issues. Select "Connection Timeout Errors" and the first error is pretty much exactly what you are looking at from the desktop. Click that and you'll end up here https://support2.microsoft.com/common/survey.aspx?scid=sw;en;3844&showpage=1

        I'd start with walking through the troubleshooting steps listed here.
