"Microsoft SQL: connection successfully established but then an error occurred during login

[mmascoli]

Hi all,

i try to connect my oracle db with MS Power BI but i have this error:

Details: "Microsoft SQL: A connection was successfully established with the server, but then an error occurred during the pre-login handshake. (provider: TCP Provider, error: 0 - An existing connection was forcibly closed by the remote host.)"

Someone can help me?

@mmascoli,

Do you connect to remote SQL Server from Power BI Desktop? And is the firewall turned on in the server that installing SQL Server? If so, please check that if you have added the TCP port and UDP port(1434) in the inbound rule of the Windows Firewall, and you can verify TCP port in SQL Server Configuration Manager.

For more details about configuring remote access for SQL Server, please review the following blog.
