Unable to connect SQL Server Database with Power Query

Hi aAmirkHan,

Thank you for reaching out to the Microsoft Fabric community Forum.

After reviewing the details regarding the issue of connecting the SQL Server Database with Power Query, please refer to the steps below to address this issue.

• Verify that the SQL Server instance has a valid SSL certificate installed. You can verify this by connecting to the SQL Server instance using SQL Server Management Studio.
• If the certificate is valid but not trusted by the client, you can configure Power Query to trust the server certificate by setting the TrustServerCertificate parameter to True in your connection string.
• Set up an environment variable named pbi_sql_trusted_servers with the name of your SQL Server. Once that is done, please restart Power Query.
• Consider switching the connection type from a Microsoft account to a Windows account, as this can sometimes resolve the issue.
• If you are operating in a less sensitive environment and wish to bypass SSL certificate validation, please add Encrypt=False to your connection string explicitly.

After making these changes, restart the SQL server and power query services to ensure the changes take effect.
