I have a PBI project connected to an SQL Azure DB.. it refresh normally from PowerBI desktop version but it fails regularly from PowerBI service, regardless if I use a gateway or not..
The error below is the same every time it fails, only the "table name" at the end of the error message get changed..
Message: Microsoft SQL: 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: TCP Provider, error: 0 - A connection attempt failed because the connected party did not properly respond after a period of time, or established connection failed because connected host has failed to respond.) Table: <Table name1 or Table name2>
