Hi,
I have Power BI desktop and have downloaded/setup the gateway to do scheduled Refresh of the data set for the Dashboard I publish. However, the refresh fails. I tried to add the connection to the gateway and I get this 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: SQL Network Interfaces, error: 25 - Connection string is not valid)"
Please advise.
