sql connection time out from power bi desktop

Hi there,

I am finding a connection timeout issue with Power BI Desktop while connecting to SQL Server 2016 CTP 2.0. I am trying to get data from AdventureWorks DimProduct and other tables, but it is failing with the below error:

"Failed to save modifications to the server. Error returned: 'OLE DB or ODBC erro: [DataSource.Error] Microsoft SQL:Connection Timeout Expired. The timeout period elapsed while attempting to consume the pre-login handshake acknowledgement. This could be becuause the pre-login handshake filed to the server was unable to respond back in time. The duration spent while attempting to connect to this serve was - [Pre-Login] Initialization=21008;handshake=1"

Any isights to this is much appreciated ?

Cheers,

Anoop
