Error: "SSL Security error" after disabling TLS on SQL Server


Environment Details

The following error occurs in an Input Data Tool after updating SQL Server to SQL 2019 and disabling TLS 1.0 and 1.1:

Error: Input Data (1): Error opening connect string: Microsoft OLE DB Provider for SQL Server: [DBNETLIB][ConnectionOpen (SECDoClientHandshake()).]SSL Security error.\08001 = 1

    • All versions
  • Ole DB
    • 18.3


The 'Microsoft OLE DB Provider for SQL Server' driver used in the Input Data tool does not support Transport Layer Security (TLS) version 1.2+.


Change the connection to use SQL Server Native Client 11.0, which supports TLS 1.2:

1. From the configuration panel, click on the drop-down arrow.
2. Click 'Data sources' > Microsoft SQL Server > OleDB.
3. Select 'SQL Server Native Client 11.0'.  (See the Additional Resources for the download link, if the driver is not available.)

4. Click 'Next' to configure the connection.
5. Click 'Test Connection' to confirm connection details are correct.
6. Click 'OK'. If the connection is successful the 'Choose Table or Specify Query' popup will be presented.
